Northland Īnanga Spawning Habitat Restoration Project | NĪSHRP

Overall native fish populations in New Zealand are in decline, including Īnanga. Part of the problem is the damage or removal of spawning habitats. Farm stock damage, man made changes to natural bank structures, sediment, barriers to fish migration as well as mowing of vegetation on banks during spawning season are contributing factors to the degredation of spawning habitats.


To scale up collaborative work locating, protecting, and enhancing īnanga spawning habitats, alongside community engagement and capacity/ capability development in the Northland region.

The project

Building connections between stakeholders and elements of co-design for local actions that improve īnanga spawning habitat and catchment health.

Supporting long term changes to improve health of spawning habitats. Such as installing temporary straw bale spawning habitat, pest control, fencing out stock, riparian planting, advice for authorities for maintenance strategies on banks and removing barriers to fish migration such as tide gates.
