Page 8 Banks Peninsula Water Management Zone Committee 16 March 2021
Ben Manson – Reported that he and Harry Millar are discussing the issue of carbon farming, mahinga kai, wetlands and fencing options that they are investigating in relation to his property. A
presentation by Ben and Harry about this will be made available to the Zone Committee members.
Aurora Smith – Advised about a visit to wetlands as part of a field day on the Stencliffe property at Pigeon Bay. This identified benefits regarding water for domestic and stock purposes and filtering nutrients - a map of the area was shown.
Benita Wakefield – Reported on the National Policy Statement for Freshwater that is giving effect to Te Mana o te Wai. This will be considered at a future Zone Committee meeting for a better understanding about it and for members to be able to filter the information out to communities. A report Benita has completed on this will be distributed to members.
Benita welcomed Matiu Payne from Koukourārata Marae to the meeting. Matiu expressed his interest in Koukourārata being able to contribute to the Committee and talked about water issues for the community.
10. Biodiversity and Land Management Ki Uta Ki Tai Catchment Approach - Selecting Priority Catchments
Gillian Jenkins outlined the process that had been worked through and criteria applied to assist in selecting priority catchments for an integrated biodiversity and land management Ki Uta Ki Tai catchment approach.
The suggested options of Wainui Bay, Ōkaruru (Goughs Bay) and Pireka (Peraki) Bay were noted. Paula Smith referred to the Canterbury Land and Water Regional Plan that discusses spending on degraded areas first, and suggested funding for a catchment other than Ōkaruru (Goughs Bay). Further consideration was given to that matter however it was noted that this was a Ki Uta Ki Tai approach. The funding split and period of time were discussed.

9. Briefing by CCC on Draft Climate Change Strategy Reference / Te Tohutoro: 21/285543 Presenter(s) / Te kaipāhō : Emma Davis, Head of Strategic Policy – [email protected]
Item 9 1. Purpose of Report / Te Pūtake Pūrongo 1.1 The purpose of this report is for the Banks Peninsula Water Management Zone Committee to be given an overview of Christchurch City Council’s Draft Climate Change Strategy, be aware of the public consultation timeframes and process, and identify how the Committee wishes to provide input.
2. Officer Recommendations / Ngā Tūtohu That the Banks Peninsula Water Management Zone Committee: 1. Agrees how they will provide their input to Christchurch City Council’s Climate Change Strategy.
3. Background Emma Davis and Marion Schoenfeld attended the Committee’s July 2020 meeting and spoke about the development of the Draft Climate Change Strategy and risk assessment for Banks Peninsula. At that meeting it was agreed that CCC would come back and talk further about the Draft Climate Change Strategy when it was closer to being ready for consultation. The Zone Committee’s Water Quantity Working Group identified at their November 2020 meeting that they had good ideas that would be useful to input to the Climate Change Strategy and they are keen to help prepare some input on behalf of the Zone Committee, and get input from other Committee members. The Zone Committee also decided at that July 2020 meeting that their role in relation to climate change impacts on freshwater on Banks Peninsula would be to help collect and share local knowledge in a way that was useful to the community, CCC and ECan. Marion Schoenfeld and Shelley Washington have had discussions with climate change engagement staff at CCC (and ECan) to develop a role for the Zone Committee that fits with this. Marion and Shelley will involve Zone Committee members in further discussions with CCC staff to progress further. At today’s meeting, Emma Davis will brief the Committee on the Draft Climate Change Strategy. Emma is Head of Strategic Policy at Christchurch City Council.
4. Report / Te Pūrongo Climate change is the biggest challenge of our time. The Christchurch District needs a comprehensive, long-term approach to climate change that addresses both the challenges and opportunities that climate change presents. The draft climate change strategy is a blueprint for collective action and part of a wider conversation about how we work together to reduce greenhouse gas emissions and plan for the ongoing effects of climate change. We recognise that Council cannot do this alone – everyone has a part to play in taking climate action. Taking action on climate change will also deliver many benefits. Our community will be able to enjoy a greener and more liveable city with healthier homes, improved air and water
Item No.: 9 Page 13 Banks Peninsula Water Management Zone Committee 16 March 2021
quality, new transport options, more trees and green spaces, and a vibrant local economy with innovative businesses and new green jobs.
By collectively committing to urgent climate action, we can create a better future for Christchurch and explore new opportunities as we transition to a low-emission, innovative and more sustainable city – a city open to new ideas, new people and new ways of doing things.
Item 9 We look forward to getting our communities’ feedback on the draft strategy which is open for public consultation from mid-March (date to be confirmed) alongside the Draft Long Term Plan. A link to the agenda of the CCC Sustainability and Community Resilience Committee that contains the decision to release the Draft Climate Change Strategy for public consultation, is below. https://christchurch.infocouncil.biz/Open/2021/02/SACRC_20210224_AGN_5363_AT_WEB.ht msdfe

10. Water Quality Ecosystem Health
Reference / Te Tohutoro: 21/285837 Presenter(s) / Te Tina Bayer, ECan – [email protected] kaipāhō :
Item 10 1. Purpose of Report / Te Pūtake Pūrongo 1.1 The purpose of this report is for the Banks Peninsula Water Management Zone Committee to be given a summary of the Environment Canterbury water quality and ecosystem health monitoring results in the Banks Peninsula zone from 2019-2020.
2. Officer Recommendations / Ngā Tūtohu That the Banks Peninsula Water Management Zone Committee: 1. Receive the summary of water quality and ecosystem health monitoring information. 2. Recommend to ECan and CCC these results be part of the knowledge base that informs decisions on any intervention projects to improve water quality and/or ecosystem health.
3. Report / Te Pūrongo Tina Bayer and Annabel Barnden presented to the Zone Committee in November 2019. After that Harry Millar worked with ECan scientists to identify where Harry may be able to support some improvements and he followed up in Pigeon Bay and Peraki Catchments. Since then, the Committee has selected the following catchments to be a priority for a Ki Uta Ki Tai Land Management and Biodiversity Advice for the next two years (2021 and 2022): Wainui Bay, Ōkaruru (Goughs Bay), and Pireka (Peraki Bay). Tina’s report today is different from past reports, so that is more of a summary of trends, aimed to be more helpful to the Zone Committee. Tina prepared the report along with Jarred Arthur and Annabel Barnden. Tina is a Scientist in the ECan Water Ecology and Ecology team.
4. Report / Te Pūrongo
WATER QUALITY INDEX The water quality index used in the CWMS targets reporting is used to summarise routine physical and chemical water quality results into five-categories for river or stream sites. The water quality index compares raw water quality data to recommended water quality guidelines; taking into consideration the number of parameters that do not meet water quality guidelines, the frequency these guidelines are not met, and by how much, to derive a score from 1-100. This score is divided into five categories and ranked to give a single grade from ‘very poor’ to ‘very good’. The water quality index is intended to provide a summary of key water quality parameters; however, it does not provide a detailed analysis of water quality data and should be used only as an indicator of overall water quality.
Banks Peninsula Water Management Zone Committee 16 March 2021
Parameters included in the index are: nitrate-and-nitrite nitrogen (NNN), ammonia- nitrogen (NH4-N), dissolved inorganic nitrogen (DIN), dissolved reactive phosphorus (DRP), total suspended solids (TSS) and Escherichia coli.
In 2019-2020 most monthly monitoring sites were rated as ‘fair’ and one site was rated as ‘poor’. As in previous years, the majority of sites failed to reach the Canterbury Land and Water Regional Plan (LWRP) standards for Bank Peninsula Rivers for dissolved reactive phosphorus and dissolved inorganic nitrogen on more than 50% of sampling
occasions. At all sites counts of Escherichia coli exceeded the LWRP standards on at Item 10 least one occasion, and at five sites more than 50% of occasions. There were no exceedances for nitrate toxicity and very few exceedances for total suspended solids and ammonia toxicity.

NATIONAL POLICY STATEMENT FOR FRESHWATER MANAGEMENT (NPS-FM) REPORTING AND LAND AND WATER AOTEREA (LAWA) TRENDS The 2020 National Policy Statement for Freshwater Management (NPS-FM) has new national bottom lines for Dissolved Reactive Phosphorus (DRP) and other water quality and ecology parameters in rivers. Most Bank Peninsula rivers are exceeding the NPS-FM national bottom line for DRP (Figure 1). Ammonia is generally low in Banks Peninsula Streams. There is a wide range of concentrations of Total Nitrogen and Turbidity (Figure 3 and 4). Most streams are in the D or E band had for E.coli, i.e. the predicted average infection risk for contact recreation is >3% (D band) or >7% (E band) (Figure 2). Five-year trends from LAWA for 7 sites (monthly monitoring) (Table 2) show that Ammonia is generally low with some improving trends Total Nitrogen and Nitrate are increasing at all sites Total Phosphorus, turbidity and black disk clarity are also degrading
Banks Peninsula Water Management Zone Committee 16 March 2021
Minimizing in-stream, bank and catchment erosion by e.g. riparian planting, stock exclusion, bank stabilization, and catchment planting can contribute to long-term
improvements in clarity, turbidity, and total phosphorus concentrations. Causes of increasing nitrate and nitrogen trends should be further investigated. A number of streams have very high E. coli median counts (Figure 2). Reduction of E. coli counts can be encouraged by stock exclusion from all waterways (both permanent and
Item 10
ephemeral) and planted riparian margins of sufficient width to intercept surface runoff.

LAKE TROPHIC LEVEL INDEX (TLI) Canterbury’s lakes are monitored for nitrogen, phosphorus, and chlorophyll a. These three parameters are combined into a single index: the trophic level index (TLI).
Banks Peninsula Water Management Zone Committee 16 March 2021
The TLI scores are categorised onto different trophic states (Table 3). In very general terms the higher the TLI the poorer the water quality.
Table 3: Description of trophic states TLI Tropic state General Description Ultra- <1 microtrophic practically pure, very clean, often have glacial sources 1-2 Microtrophic very clean, often have glacial sources, very low nutrient enrichment
Item 10 2-3 Oligotrophic clear and blue, with low levels of nutrients and algae 3-4 Mesotrophic moderate levels of nutrients and algae 4-5 Eutrophic green and murky, with higher amounts of nutrients and algae 5-6 Supertrophic very high nutrient enrichment and high algae growth >6 Hypertrophic saturated in nutrients, highly fertile, excessive algae growth
Te Roto o Wairewa / Lake Forsyth was classified as supertrophic in 2019/2020 as it continued to be highly enriched in nutrients and phytoplankton biomass (Table 4). The Land and Water Regional Plan objective of a TLI score of 5.0 by 2030 has not be reached yet. Lake Forsyth seems to go through periods of improving and deteriorating TLI (Figure 5), so these results need to be interpreted with caution. However, both total nitrogen and total phosphorus concentrations in the lake have been decreasing significantly between 2009 and 2019.

CONTACT RECREATION The microbial quality of water is monitored each summer at popular freshwater (rivers and lakes) and coastal (beaches, bays and estuaries) bathing sites in Canterbury. Water
samples are collected weekly to measure concentrations of faecal indicator bacteria (E. coli and/or enterococci). This data is reported to Community and Public Health (CPH) and Territorial Local Authorities (TLAs), and used to assess and communicate the public health risk of swimming at bathing sites.
Weekly sampling results that exceed single sample health guidelines for bacterial Item 10 concentrations in water are reported to CPH and TLAs as soon as possible to issue public warnings to the community. Five-yearly data is also used to calculate suitability for recreation grades (SFRGs) specific to each bathing site (Table 5). Any site with an SFRG of ‘fair’ or better is considered to be generally suitable for contact recreation. The Land Air Water Aotearoa website (https://www.lawa.org.nz/explore-data/swimming/) contains gradings for all bathing sites and is updated daily with the most recent monitoring results.
Table 5: Contact recreation grades for bathing sites monitored in the Banks Peninsula CWMS zone. Grades will be adopted for the 2020/21 bathing season. Suitability for Recreation Grade Change Site (*excludes rainfall data) in 2015/16 2016/17 2017/18 2018/19 2019/20 grade Cass Bay Good Good Good Good Good Church Bay Good Good Good Fair Fair Corsair Bay Good Good Good Good* Good* Diamond Harbour Good Good Fair Fair Good* ^ Beach Paradise Beach Very Good Very Good Good Good Good Pūrau Bay Good Good Good Good Good Rāpaki Bay Good Good Good Good Good Sandy / Governors Good Good Good Fair Poor Bay Akaroa main beach Good Good Good Good Good Duvauchelle Good Good Good Good Good Very Very Good Very Good Very Good Very Good French Farm Good Glen Bay Very Good Very Good Good Good Good Okains Bay Estuary Good Good Good Good* Good* Takamatua Good Good Good Fair Fair Tikao Bay Good Good Good Fair Fair Wainui Beach Good Good Good Good Good ^ Improvement in SFRG at Diamond Harbour Beach is only because rainfall affected data is removed for 2019/20 grading i.e. rainfall affected data not removed in previous seasons gradings.
All but one bathing site within the Banks Peninsula Zone are considered suitable for primary contact recreation (Table 5). The exception is Sandy / Governors Bay which decreased a grade from ‘fair’ to ‘poor’ in 2019/20. Diamond Harbour Beach increased a grade from ‘fair to ‘good’ in 2019/20, while all other sites remained unchanged from the
Banks Peninsula Water Management Zone Committee 16 March 2021
previous season. The reason for why Sandy / Governors Bay decreased a grade and is now not recommended for swimming is unknown. Environment Canterbury is planning to investigate this further over the 2020/21 summer by monitoring the number of birds
congregating at the site and undergoing faecal source tracking if suitable.
CYANOBACTERIA Environment Canterbury monitors phytoplankton concentrations (including planktonic
cyanobacteria) in Te Wairewa/Lake Forsyth on a monthly basis. Protocols have been Item 10 established with Community and Public Health and Christchurch City Council in accordance with MfE & MoH (2009), outlining further monitoring and response requirements if thresholds are exceeded which indicate a potential health risk. The alert-level framework is based on biovolume thresholds derived from both total cyanobacteria cell counts and potentially toxic cyanobacteria cell counts. Monitoring frequency is increased if either of the thresholds is exceeded. If the action trigger level is exceeded, then signage is erected to warn the public of the health risk and a media release is issued. Information is also placed on the Environment Canterbury website and Land Air Water Aotearoa (www.lawa.org.nz) when warnings are issued. In the 2019/2020 season two health warnings were issued: A small, relatively short bloom of Aphanizomenon cf. gracile was detected in late September. While the lake was clear of cyanobacteria for most of the summer, a bloom of Nodularia persisted for several months in Lake Forsyth / Te Wairewa between late March 2020 and August 2020 (Table 6).
Table 6: Summary of Lake Forsyth / Te Wairewa warnings issued for planktonic cyanobacteria blooms over the 2019/20 summer.

ECOSYSTEM HEALTH Environment Canterbury collect macroinvertebrates and habitat information at a number of sites on Bank Peninsula as part of their annual Aquatic Ecosystem Health (AEH) monitoring programme. Aquatic ecosystem health can be determined by finding out what critters (e.g., macroinvertebrates) are living in a waterway. Macroinvertebrates are the small animals without a backbone. In streams these include worms, snails, insects and other small animals living on or within the streambed. Macroinvertebrates are a good indicator of stream health because they live in the stream throughout the year and will respond over time to changes in water quality, surrounding land use and the physical instream habitat (e.g., changes in amount of fine sediment or algae).
Macroinvertebrates have varying responses to water and/or habitat quality (Figure 6). For instance, some taxa are more sensitive to declining water and/or habitat quality and therefore will be more likely to suffer from degradation; however other taxa that
Banks Peninsula Water Management Zone Committee 16 March 2021
are more tolerant to poorer habitat and/or water quality are likely to be found in higher abundances when habitat and/or water quality is compromised. Analysis and interpretation of the macroinvertebrate data will often consider the abundance of taxa
that are sensitive or tolerant to degraded water and habitat quality.

Changes to macroinvertebrate communities can usually be related back to changes to habitat, water quality and/or water quantity. However, it’s not typically one factor but often several that can result in a change to macroinvertebrate communities. For example, elevated nutrient concentrations (e.g., nitrogen and phosphate) may affect stream macroinvertebrates directly through toxicity, or indirectly through supporting increased aquatic plant growth which in turn can lead to large oxygen fluctuations, channel choking, and even increased sediment entrapment. River flow is also a strong influencing factor on overall macroinvertebrate health due to the instream conditions associated with any given flow. For example, in drier years low flows can favour taxa with a higher tolerance to warmer water temperatures or excessive periphyton growth. In contrast, higher flows help keep water temperatures down, prevent the build-up of fine sediment and streambed periphyton and generally result in a higher number of the sensitive or the intolerant taxa being found. However, at the extreme end, floods may temporarily reduce macroinvertebrate diversity and abundance due to displacement and mortality. Macroinvertebrates and habitat data collected by Environment Canterbury from each site is summarised and used to calculate macroinvertebrate (biotic) and habitat health grades. We have shown biotic and habitat health grades here to provide a summary of health of streams in the Banks Peninsula zone. Note that health grades were designed originally to identify general trends across river flow types (e.g., hill-fed, banks peninsula) and not to necessarily to characterise individual sites. Thus, health grades should only be used as a broad scale indicator of stream health at the individual site level. Figure 7 summarises macroinvertebrate health grades for Banks Peninsula and shows the proportion of sites within each health grade category between 2008/2009 and 2019/2020. Figure 8 shows stream macroinvertebrate and habitat health grades calculated at 24 Aquatic Ecosystem Health (AEH) monitoring sites during the 2019/2020 summer season. Tabulated grades and plots showing macroinvertebrate and habitat grades are presented in Tables 7 and 8 as well as Appendix 1.2.
Banks Peninsula Water Management Zone Committee 16 March 2021
It is not uncommon for macroinvertebrate and habitat health grades to vary between sites or over time within sites. Generally, macroinvertebrate communities on Banks Peninsula are healthiest towards the head waters of the stream. These areas typically
have relatively intact riparian vegetation which is dominated by native species and as a whole there has been a lower amount of stream modification. As with many of the river- type categories, the lowest health grades on Banks Peninsula are generally found lower down catchments. These stream reaches tend to have been impacted by increased land use change (e.g., farming or urban), and may have little or no riparian buffering from
Item 10
adjacent land uses. Further, the lower gradients make these stream reaches highly susceptible to deposition of any fine sediment entering the stream. In brief, factors that are associated with poorer ecosystem health in the Banks Peninsula streams include:
Direct stock access and/or pugging of stream banks which can lead to trampling of bank vegetation and bank erosion, Lack of intact ground cover or riparian vegetation leads to higher amounts of runoff and sediment entering waterways, Lack of overhead riparian cover can result in higher summer water temperatures (and subsequently can result in higher amounts of algal growth), Excess fine sediment and deposition smothers the bed substrate and limits the type and amount of habitat available for macroinvertebrates to colonize.
The discrepancy that is sometimes observed between macroinvertebrate and habitat grades (i.e., poor macroinvertebrate health grades but good habitat health grades) could indicate that there is only a couple of habitat parameters that are scoring low, thus if the majority of habitat parameters are scoring high there will still be a high habitat grade overall. This is important as it highlights that there may be some habitat parameters, such as substrate embeddedness or sediment deposition, that are having a greater direct influence on macroinvertebrate community composition. Of course, water quality can also be a key driver to shape the composition of macroinvertebrate communities and should also be considered in any system. Figure 7 shows an apparent improvement in macroinvertebrate health grade between 2015/20216 and 2019/2020. However, during this period water quality declined (Table 2). River flows were low in 2015/2016 and sediment cover high. Water temperature data is inconclusive. It is likely that a reduced sediment cover (that may be linked to riparian planting and stock exclusion) and high river.

11. Wainui Stream E.coli Reference / Te Tohutoro: 21/287271 Presenter(s) / Te kaipāhō : Jarred Arthur, ECan – [email protected]
1. Purpose of Report / Te Pūtake Pūrongo Item 11
1.1 The purpose of this report is for the Banks Peninsula Water Management Zone Committee to be given the results of analysing past E. Coli water quality data for Wainui Stream in relation to stream flow.
2. Officer Recommendations / Ngā Tūtohu That the Banks Peninsula Water Management Zone Committee: 1. Receive the information in the Wainui Stream E.coli report.
3. Background Jarred Arthur (Senior Scientist – Water Quality and Ecology, ECan) attended the Zone Committee meeting held at Wainui in September 2020 where Edward Challies and Mike Bourke presented the summary of the findings of the research done over the 2019-20 Summer on Wainui Stream water quality analysis and survey of onsite wastewater management systems. One of the recommendations the Zone Committee made at that meeting was to ask Environment Canterbury to consider the research when it presents the annual water quality results for Banks Peninsula and provide advice to the Committee about possible next steps. Jarred has analysed the past data for Wainui Stream in relation to the research presented last September, and has prepared this report. Jarred is not able to attend this meeting, so Tina Beyer has included his content in her presentation on water quality and ecosystem health monitoring results in the Banks Peninsula zone from 2019-2020. Jarred does not have advice about possible next steps as the results of his analysis does not change the findings presented in September and the Zone Committee’s recommendations are still valid and the intention is to implement them. For example, that the Land Management Advisor work with landowners to encourage reticulated stockwater and waterfowl control and that a community engagement plan be developed to raise awareness of residents about effective on-site wastewater management. Wainui Catchment is now one of the three catchments selected by the Zone Committee for an integrated Biodiversity and Land Management Ki Uta Ki Tai Catchment Approach, so the Land Management Advisor and Biodiversity Advisor along with the Committee’s support will be working closely with the Wainui Catchment community on a variety of actions agreed to by the community. Jarred notes that it is important that the Zone Committee considers the findings of the Wainui Stream Study report when drawing their own conclusions, so a reminder of the findings is provided below.
Item No.: 11 Page 43 Banks Peninsula Water Management Zone Committee 16 March 2021
Reminder of Findings of the Wainui Stream Study report (taken from the executive summary):
Water quality results show elevated levels of E. coli in the lower catchment of the Wainui Stream. These appear to be mainly from avian and bovine sources, but also indicated minor traces of human sources. Fluorescent whitening agents were also detected in Wainui Stream, but these were not consistently present and never exceeded ‘slight’ presence. The water quality results are therefore inconclusive regarding wastewater contamination. DRP results
Item 11 were high relative to water quality guidelines for ecosystem health, but not unusual for a rural catchment.
The residents survey confirmed high occupancy in Wainui over the summer holiday period – especially over Christmas and the New Year. At this time of year onsite wastewater systems come under particular strain, and some residents reported having observed problems with their systems at such times, and often following heavy rainfall. Many onsite systems appear to be relatively old, and possibly not up to current standards. Some residents expressed a desire to better understand their systems and what is good practice for onsite wastewater management. Many residents expressed concern about the state of uncertainty in relation to whether or not a reticulated wastewater solution would be implemented for Wainui.
During the course of the investigation, there was not strong evidence that wastewater from private onsite treatment systems was a dominant source of faecal contamination to Wainui Stream. However, given the slight presence of human markers and FWAs in the results, it is possible that inputs of human contamination could enter the stream under certain circumstances. Factors such as rainfall and visitor numbers may influence the relative contribution of human-derived bacteria versus agriculture- and avian-derived bacteria instream. Longer-term studies may therefore help to establish with more certainty whether wastewater contamination is a significant issue for Wainui Stream.
4. Report / Te Pūrongo
Please find attached a one page Wainui Stream E. coli graph for the Zone Committee’s information. Summary points are: 4.2.1 There appears to be a seasonal pattern of high E. coli occurring in Wainui Stream over summer. This pattern suggests that there may be a correlation of high E. coli in water with holiday periods when peak occupation is observed in local dwellings. Note that this seasonal pattern of variable water quality was what in-part drove the Wainui Stream study in 2019/20. 4.2.2 Stream flow is not monitored in Wainui Stream, however the neighbouring French Farm Stream represents the likely flow conditions in Wainui Stream over time. Stream flow in this graph is represented as the mean daily flow on any given day that E. coli data was collected (despite the line graph suggested it is continuous data over the entire period). It was easier to graph this way. 4.2.3 As a rule of thumb, high rainfall and flow is generally correlated with high E. coli concentrations in rivers due to the increased runoff of land based contaminants. The
Item No.: 11 Page 44 Banks Peninsula Water Management Zone Committee 16 March 2021
graph shows, however, that there are other drivers of poor water quality in the Wainui Stream catchment.
4.2.4 It is important that the Zone Committee considers the findings of the Wainui Stream Study report when drawing their own conclusions.

3. The Zone Committee The Banks Peninsula Zone Committee is established under the auspices of the Local
Government Act 2002 in accordance with the Canterbury Water Management Strategy 2009. The Committee is a joint committee of Christchurch City Council and Environment Canterbury. The purpose of the Committee is to: Uphold the mana of freshwater bodies within their zone by facilitating enduring land and
Item 12 water management solutions that give effect to the Canterbury Water Management vision, principles and targets in their zone. The functions are to: 3.4.1 Facilitate community engagement and collaboration – continuing an active programme of engaging with communities on freshwater management matters; and 3.4.2 Facilitate the provision of advice through to councils (relevant Territorial Authorities and Environment Canterbury) and others (e.g. private sector) contributing to freshwater management; and 3.4.3 Enhance delivery capability and coalition of the willing – working with stakeholders across all sectors to extend the resources available to implement the CWMS, including connecting others to additional resources and seeking opportunities to promote, support, leverage and expand catchment-based initiatives that deliver the CWMS; and 3.4.4 Provide progress reports – annual progress reporting to Councils and Rūnanga on progress towards delivery of the zone-specific priorities and CWMS target areas identified in the Zone Committee Action Plan. The Committee does not have the authority to commit any council to any path or expenditure and its recommendations do not compromise the Council’s freedom to deliberate and make decisions. The Committee does not have the authority to submit on proposed Resource Management or Local Government Plans. The Committee does not have the authority to submit on resource consent matters.
4. Operating Philosophy The Committees will at all times operate in accordance with the requirements of the Local Government Official Information and Meetings Act 1987, and will observe the following principles: 4.1.1 Give effect to the Fundamental Principles, Targets and goals of the CWMS;
4.1.2 Be culturally sensitive observing tikanga Maori;
4.1.3 Apply a Ki uta ki tai (from the mountains to the sea) approach;
4.1.4 Work with the CWMS Regional Committee to support the implementation of the CWMS across the region as a whole;
Item No.: 12 Page 48 Banks Peninsula Water Management Zone Committee 16 March 2021
4.1.5 Give consideration to and balance the interests of all water interests in the region in debate and decision-making;
4.1.6 Work in a collaborative and co-operative manner using best endeavours to reach solutions that take account of the interests of all sectors of the community;
4.1.7 Contribute their knowledge and perspective but not promote the views or positions of
any particular interest or stakeholder group; Item 12
4.1.8 Promote a philosophy of integrated water management to achieve the multiple objectives of the range of interests in water;
4.1.9 Seek consensus in decision-making where at all possible. In the event that neither unanimous agreement is able to be reached nor a significant majority view formed, in the first instance seek assistance from an external facilitator to further Committee discussions and deliberations. Where the Committee encounters fundamental disagreements, despite having sought assistance and exhausted all avenues to resolve matters, recommend that the respective Councils disband them and appoint a new Committee.
5. Elections 5.1 Each year, the Committee is required to appoint the Chair and Deputy Chair from the membership by simple majority. There is no limit on how long a person can be in either of these positions. 5.2 The Committee also needs to appoint a member to the position of representative on the regional committee.
Process to Elect of Chair and Deputy Chair (ref. Christchurch City Council Standing Orders)
5.3 A local authority or a committee (if the local authority has so directed) must determine by resolution that a person be elected or appointed by using one of the following systems of voting:
(a) [System A]; or (b) [System B].
System A
(a) requires that a person is elected or appointed if he or she receives the votes of a majority of the members of the local authority or committee present and voting; and
(b) has the following characteristics: (i) there is a first round of voting for all candidates; and
(ii) if no candidate is successful in the round there is a second round of voting from which the candidate with the fewest votes in the first round is excluded; and
Item No.: 12 Page 49 Banks Peninsula Water Management Zone Committee 16 March 2021
(iii) if no candidate is successful in the second round there is a third, and if necessary subsequent round of voting from which, each time, the candidate with the
fewest votes in the previous round is excluded; and
(iv) in any round of voting, if 2 or more candidates tie for the lowest number of votes, the person excluded from the next round is resolved by lot.
System B Item 12
(a) requires that a person is elected or appointed if he or she receives more votes than any other candidate; and
(b) has the following characteristics:
(i) there is only 1 round of voting; and
(ii) if 2 or more candidates tie for the most votes, the tie is resolved by lot.”

2. Officer Recommendations / Ngā Tūtohu That the Banks Peninsula Water Management Zone Committee: 1. Receives the information in the Facilitator’s update report.
3. Important Zone Committee/CWMS updates
3.1 A new version action plan will be workshopped in April and May. This will be simpler and easier to communicate and aligned with the new purpose, functions, and Council letter of shared priorities. The new version includes the actions from the action plan the Committee has been using, with some tweaks. A document has also been drafted that can be used for progress tracking with “what the committee will do”, “progress updates” and “we will measure our success by”. This will help the Zone Committee know where they are up to with their actions and to aid development of three-monthly and annual reporting to CCC and ECan. 3.2 The refresh process to seek new Zone Committee members will happen during May with advertising starting in April after Long Term Plan consultation concludes. 3.3 Reporting to CCC Three Waters Committee is changing from quarterly to three-monthly and the same is being set up for reporting to ECan. The Annual Report will be presented at the same time as one of these three-monthly reports. 3.4 There are no longer Zone Committee representatives on the Regional Committee. 3.5 Elizabeth MacPherson has returned from a leave of absence taken and Benita Wakefield has resigned from the role of Chair but will remain on the Zone Committee as the Wairewa Rūnanga representative. The Koukourārata Rūnanga representative position remains vacant.
