My full name is Paula Gay Warren. 2. I hold a Bachelor of Science in botany and ecology from the University of Auckland. I have undertaken some post-graduate studies, and continue to carry out voluntary scientific work as a liverwort parataxonomist. 3. I have 24 years professional experience as a central government policy analyst, primarily working on legislation and systems reforms for conservation and environmental management. I have had a range of policy and management roles and am currently employed as a Principal Policy Analyst in the Department of Conservation. I am presenting this evidence in a private capacity, not as an employee of the Department. 4. I have worked on a wide range of legislation and systems reforms in New Zealand. 5. I was involved in the development of the Resource Management Act, including working on secondment to the Ministry for the Environment in finalising the policy and developing the drafting instructions for the Resource Management Bill provisions relating to coastal management, and 1 participating in the select committee process for the Bill. I have subsequently worked to a lesser or greater degree on subsequent reforms of the Resource Management Act and the development of national policy statements and national environmental standards. 6. I have been a statutory decision-maker in the Department of Conservation. For a period in the early 1990s I was responsible for all mining decisions – either approving mining operations under delegation or making recommendations to the Minister of Conservation. That work gave me a clear understanding of the complexity of decisions that involve weighing up competing values, and the importance of ensuring that decisions are made in accordance with the provisions of the relevant statute and in accordance with the principles of natural justice. My work included recommending approval of a major mine that would have significant impacts on conservation values, but where analysis in terms of the statutory provisions indicated that such approval was the correct outcome in legal terms. 7. I have also undertaken international work. I was New Zealand’s principal technical delegate to the Convention on Biological Diversity for a number of years, was a member of the technical body Bureau, represented the Convention in other international processes, and chaired meetings. I was also the Clearing House Mechanism Focal Point for New Zealand, and in that role carried out extensive work to foster scientific and technical cooperation between New Zealand and other countries. That has included doing work with agencies in Chile, Mexico, and Argentina. 8. I have also worked with the Galapagos as a volunteer for the last decade, helping develop biosecurity regulations and systems. That has provided me with experience in applying scientific principles and policy approaches in a very different legal and social context. 9. I have been actively involved in transport as an advocate for users of public transport and pedestrians for most of the last two decades. I am the user representative on the NZ Transport Agency national Passenger Transport 2 Advisory Group, and have been an appointed member of the Wellington Regional Land Transport Committee. 10. As a member of the Regional Land Transport Committee, considering a different Transmission Gully Project proposal, in a different context, I voted in favour of its inclusion in the RLTS. But I have made a submission against this application, because the analysis I have undertaken as a policy expert with a strong understanding of ecology and transport has led me to the conclusion that the application should not be accepted. 11. I have read the Code of Conduct for Expert Witnesses (March 2011) as contained in the Environment Court Consolidated Practice Note (2006), and I agree to comply with it. Although I have submitted against this proposal I have drafted my evidence as far as possible in compliance with the Code, relating my expertise in the areas outlined above to the project and the considerations under the RMA. 12. In my evidence I have sought to draw together relevant information in scientific papers, the grey literature, statutes and statutory documents, to provide an analysis of the proposal. 13. I have included all the relevant material that I have identified, and sought to reach a policy conclusion based on that material. Where the material is contradictory, I have sought to identify the most appropriate overall response to those contradictions. I do not claim that the material I have identified is a comprehensive selection, as in the limited time available and with no financial resources, a full search of the literature and other sources has not been possible, but I have not excluded any material that I am aware of that I believe to be relevant. If I had had available alternative evidence, I may well have reached a different conclusion from a policy perspective (as I did when considering alternative information about an alternative TGP in the Regional Land Transport Strategy context.) 3 SCOPE OF EVIDENCE 14. My evidence firstly considers offsetting, largely from a theoretical perspective. 15. It then considers the effects TGP may have on freshwater and the coastal marine area, and the relevant statutory requirements relating to those effects and the plan change as it relates to those effects. 16. It then examines the costs and benefits of the TGP, and considers their relevance in the statutory context, particularly as it relates to infrastructure and transportation matters. OFFSETTING 17. The issue of offsetting is clearly critical to the consideration of this proposed plan change. 18. I was responsible for developing an approach to compensation, including offsetting, for mining operations on land administered by the Department of Conservation. I also had responsibility for the policy relating to amendments to conservation legislation that replaced provisions relating to the way compensation was considered in concession processes. I have therefore looked closely at the way offsetting can operate, and the way various forms of offsetting relate to various statutory codes. What is offsetting – mitigation or compensation? 19. Mr Milne’s advice highlights the need to clearly distinguish between offsetting which is a subset of mitigation and offsetting which is a subset of compensation. 4 20. Making that distinction is, in my view, important (in general and in the current instance) to provide clarity about how offsets should be treated in statutory decisions. 21. It appears that NZTA intends offsets to be something other than mitigation, given that the term is added to a list that includes the term ―mitigation‖. 22. The proposed NPS on Indigenous Biodiversity, which is cited in the evidence of Mr Daysh, defines a biodiversity offset as follows: Biodiversity offset means measurable conservation outcomes resulting from actions which are designed to compensate for more than minor residual adverse effects on biodiversity, where those affects arise from an activity after appropriate prevention and mitigation measures have been taken. The goal of biodiversity offsets is to achieve no net loss and preferably a net gain of biodiversity on the ground with respect to species composition, habitat structure and ecosystem function. 23. An important aspect of that definition is that offsets compensate for residual adverse effects. They do not prevent those adverse effects occurring. 24. Offsetting is, under that definition, not part of avoiding, remedying or mitigating. It is compensation for those effects that cannot be avoided, remedied or mitigated. Offsetting and protection 25. Nor can that type of offsetting be part of protection, because it does not reduce the effect on the resource being protected. 5 26. At one of the meetings held to discuss the Freshwater Plan change proposal, a member of the public put it this way: “I am responsible for protecting my children. So under that idea, if I leave them at home every night without food, and go out and save other children from worse abuse, I am still protecting my children because NZ children are, overall, better off? I think not. The Police would still rightly prosecute me for not protecting my children.” 27. I do not consider that compensatory offsetting can provide any contribution to the achievement of a sustainable management objective in line with the section 6 requirement to provide for the protection of natural character from inappropriate subdivision, use and development. 28. Equally, it could not be cited as achievement of avoidance, because it does not reduce the severity of the effect on the resource. 29. Whether mitigating offsets can achieve protection of natural values or avoidance will be explored further below. What actions to improve biodiversity could be considered to be mitigation 30. I have examined this question from a biological perspective, and reached a similar conclusion to Mr Milne. 31. Biologically, mitigation does not have to be at the same site. But it does have to address the specific effect of the development, and therefore the same biological characteristic that is being affected. 32. For example a development may reduce the breeding success of a bird species by reducing its food supply. An activity that increased the breeding success of that population by controlling predators at nesting sites some distance from the feeding area would be mitigation. An activity that increased the breeding success of a different population or different species, even if at the same site 6 as the effect, would not be, because it would not reduce the severity of the effect. 33. Mr Milne has highlighted that the resource being protected may be defined at various scales.
