NPS(FW) - Fish Passage Support tools


Many of New Zealand's freshwater fish species need to move within waterways, and some need to move between freshwater and the sea (e.g. whitebait and eels) as part of their life-cycle. They move to access habitats necessary to support different life-stages (e.g. reproduction and rearing) and ecological functions (e.g. feeding or finding refuge).

Instream structures, such as culverts, weirs and dams, can delay or prevent fish movements if not designed, installed or maintained well to provide passage. This can result in a reduction in the distribution and abundance of some of our most iconic and valued freshwater species.

Today, more than 70% of our native freshwater fish are at risk of or threatened with extinction.

The National Policy Statement for Freshwater 2020 provides local authorities with updated direction on how they should manage freshwater under the Resource Management Act 1991, including provisions for fish passage.

The National Environmental Standards for Freshwater 2020 regulate activities that pose risks to the health of freshwater and freshwater ecosystems, including fish passage risks.

This presentation will highlight the efforts of the NZ Fish Passage Advisory Group in supporting these fish passage policies and regulations providing  lessons learnt and highlighting some of the opportunities for improvement available to environmental compliance officers to address some of the fish passage issues currently being faced on the ground.
