As we reach the midway point of 2026, the BTW Ecology Team has reflected on the freshwater ecology work completed so far this year.
The team has delivered freshwater fish salvage and relocation across multiple projects, supporting clients to minimise the effects of in-stream works and habitat modification. This represents an increase in fish-related work compared with previous years and reflects the growing demand for specialist freshwater ecology services.
In addition to freshwater fish, the team also carefully relocated freshwater shrimp and other aquatic invertebrates where required, helping to reduce environmental effects during project delivery. The management, handling, and relocation of these taonga freshwater species have all been undertaken in accordance with our relevant permits and associated conditions.
Several projects were mobilised within short timeframes through BTW’s nationwide permit for freshwater fish recovery and relocation, enabling the team to respond efficiently while ensuring environmental and regulatory requirements were met.
Working alongside hapū and communities
An important part of this mahi has been working alongside hapū and communities to build knowledge and capability.
Throughout the year, the team has partnered with hapū across the North Island, particularly in Taranaki, to support training in the safe handling and relocation of taonga freshwater species. These partnerships recognise the importance of working collaboratively and incorporating local knowledge, values, and aspirations into environmental management.
Fieldwork has also provided valuable insights into the condition of freshwater ecosystems. Across several project sites, the team encountered Threatened and At-Risk species such as īnanga, banded kokopu, longfin tuna, kākahi (freshwater mussels), redfin bully, and torrentfish.
Delivering this work has required a busy summer and, unusually, an equally active autumn, reflecting the diverse range of projects underway across the country.
Ngā mihi nui to the communities, hapū, clients and project partners who have contributed to and supported this mahi. Their collaboration and commitment have been integral to achieving positive environmental outcomes.
The Ecology Team looks forward to continuing to work alongside partners to protect and enhance Aotearoa’s freshwater environments throughout the 2026/27 season.
