2023 NZPI CONFERENCE PRESENTATION
SESSION: Thursday 20th April
PRESENTED BY: Sam Morgan
It is understood that the proposed Climate Change Adaptation Act (CAA) will seek to address to some of the potential challenges that arise with managed retreat. However, it is likely that this will only provide highly level guidance.
Often the discussion of managed retreat starts after a significant storm or erosion event at a time when immediate action is more likely needed. The reality is that implementing an efficient and effective retreat programme takes many years with significant hurdles to be overcome. Starting the process after an event inevitably leads to delay while working through what is often heated debate about the pros and cons over more traditional management approaches.
This presentation will consider recent examples from around New Zealand to show how even when there is community buy-in to a managed retreat regime, the process can then be stymied by resource consent and building consent processes, or where it has simply been challenged as an unnecessary intervention from the outset.
What is required is to recognise the need to act early, use past examples to demonstrate the need effectively and how common obstacles to implementation can be overcome. It is likely that a more effective approach will be to develop and implement a range of planning strategies. It is vital to act locally, in a way that builds on the early lessons from across New Zealand, that also considers the value of adopting varying time scales for implementation. This presentation will look at the application of the Dynamic Adaptive Pathways Planning framework to various Shoreline Management Plans (SMPs) being developed in different parts of the country and discussion will be given to the various scales of SMPs required to achieve the various outcomes required moving forward.
