Our team conducted a total of twenty-nine interviews with the Rangitāne (Māori), Department of Conservation, South Wairarapa District Council, landowners, and recreational water users regarding the Blundell Barrage Gates which play a vital role in flood management. Interview discussions indicate that water quality, sources of pollution, water levels, flood management, and future operation of the barrage gates are controversial. We identified communication, collaboration, and education as three areas of focus for the GWRC as they continue to improve their management of the region. i Executive Summary This project is concerned with Wairarapa Moana, a water system located in the Wairarapa region, situated on the North Island of New Zealand. Wairarapa Moana consists of the three main water bodies, shown in Figure 1; the coastal lake is Lake Onoke, the inland lake is Lake Wairarapa, and the main river is the Ruamahanga. The system is dynamic, which means water can flow in both directions. Both tidal movements and rainfall affect the direction of flow. The area is low-lying and sits between two mountain ranges exposing much of the land to seasonal flooding. The Greater Wellington Regional Council, the governing body for the Wellington region, developed the Lower Wairarapa Valley Development Scheme (LWVDS), to control flooding in the 1960s. This scheme includes the diversion of the Ruamahanga River around Lake Wairarapa and the implementation of the Blundell Barrage Gates as shown in Figure 1. Figure 1 - The Lower Wairarapa Valley Development Scheme, which contains the diversion of the Ruamahanga straight into Lake Onoke and the Blundell Barrage Gates, dramatically reduced the extent of flooding, as shown in light blue (Google, 2015). The Wairarapa community is currently experiencing a resource management conflict regarding the flood prevention scheme. The conflict involves many different stakeholders within the region. The tensions stem from the historic difference in lifestyle between the Pakeha and the indigenous Māori. Pakeha refers to non-Māori individuals, primarily English colonists who began settling in the Wairarapa region in the 1840s. The British Crown and the Māori signed the Treaty of Waitangi in 1840, which established British sovereignty over New Zealand. Over the years, it became clear that the Māori and the Pakeha valued the land differently. Where the Māori value the land for its intrinsic value, the Pakeha generally value the land for its economic value. In Wairarapa Moana, the land would routinely flood and drain. Conflicts arose around ownership of the lake bed and who would control the flooding of the lake. The farmers desired flood control in order to protect their assets, land and animals, and the Māori desired higher water levels for catching eels. Inevitably, pressure from the British Crown to sell, left the Māori no choice but to gift their land to the Crown in 1896. In 1975, the government formed the Waitangi Tribunal in ii order to hear claims of breaches in the Treaty of Waitangi. Rangitāne o Wairarapa, a local Māori tribe or iwi, initiated a settlement claim with the Office of Treaty Settlements and is currently working to settle overlapping claims with a second iwi, the Kahungunu ki Wairarapa. The outcome from this settlement may result in the Crown gifting the lake bed back to both tribes. This could lead to greater iwi involvement, affecting the scheme the Greater Wellington Regional Council currently uses to manage the lake. The Greater Wellington Regional Council (GWRC) dramatically altered the landscape over the last fifty years with the implementation of the Lower Wairarapa Valley Development Scheme. The New Zealand Resource Management Act of 1991 mandates that most activities that affect the environment obtain a resource consent. The GWRC flood protection department is responsible for renewing their two resource consents for maintaining the entire scheme and operating the Blundell Barrage Gates. The resource consent that permits the usage of the barrage gates will be up for renewal in 2019 and the resource consent that permits the management of the entire Lower Wairarapa Valley Development Scheme will require renewal in 2025. The aim of the Greater Wellington Regional Council is to utilize our team as a third party to investigate and discover the thoughts and opinions of the concerned stakeholders in the region. They tasked us with speaking to the Rangitāne o Wairarapa, the Department of Conservation, South Wairarapa District Council, landowners, and recreational water users so that they may better prepare for the resource consent renewal. This project’s focus was to detail the points of view of each stakeholder group and improve communication within the Wairarapa Moana community regarding the management of Lake Wairarapa. In order to achieve this goal, our team developed three objectives: 1. To observe and gain understanding of the current political, ecological, economic, and cultural situation in Wairarapa Moana 2. To identify the perspectives and needs of each stakeholder group regarding the management of Lake Wairarapa 3. To determine common interests, concerns, and major differences by highlighting recurring themes regarding the Blundell Barrage Gates. To achieve our main goal of detailing the points of view of each stakeholder group, we utilized three methods: background research, interviews, and data analysis. Through observing Lake Wairarapa, a Wairarapa Coordinating Committee meeting, and a welcoming ceremony at the Kohunui Marae, the project group developed a thorough understanding of the region and community. We interviewed David Boone, the section leader of the Flood Protection Department at the GWRC, who provided us with intricate knowledge of the flood protection scheme. These activities allowed us to align our project objectives to better match the needs of the flood protection department. After familiarizing ourselves with the region and its people, our team identified the perspectives and needs of each stakeholder group by conducting and transcribing twenty-four semi-structured interviews with twenty-nine individuals as shown in Table 1. Semi-structured interviews allow free discussion, containing a set list of questions, while offering flexibility to ask supplemental questions. Each stakeholder group had a unique interview protocol, which inquired about the same topics but the wording of the questions varied depending on the specific interest of the group interviewed. iii Table 1 - Stakeholder Breakdown Stakeholder Interviewee Breakdown (29 total): Department of Conservation: 7 Rangitāne o Wairarapa: 4 South Wairarapa District Council: 6 Landowners: 8 Recreational Water Users: 4 After we completed the interviews, we coded the information by recurring themes in the responses. Independently, three group members each coded roughly a third of the transcripts from the interviews and the last member reviewed, summarized and sorted the coded data into the respective topics. This allowed us to transform our qualitative raw data into quantitative data and draw conclusions regarding common and differing interests of each stakeholder group. Our data and analysis highlights five key points of contention: water quality perceptions, sources of pollution, flood management, future operation of the scheme and water levels. For stakeholder perceptions of water quality, only two respondents indicated that the current quality of the water was good. The breakdown of responses by stakeholder is shown below in Figure 2, which indicates that generally, interviewees thought that the water quality was poor or neutral. Figure 2 - Table of water quality perceptions It was brought to our attention, before the start of the interviews, that the public generally considered farming practices as a main cause for the poor water quality in the region. However, the interviewees noted several other factors that affect the quality of the water. If at least fifty percent of a stakeholder group mentioned a factor of water quality, we noted it and included it in Figure 3, below. Nineteen out of the twenty-nine
