The Return of Inanga at Whitiwhiti

Wetlands and waterways play an important role in the health of both the environment and the communities that surround them. 

At Whitiwhiti, recent restoration work is beginning to show exactly why that matters, with the discovery of tiny inanga eggs along the Waiomoko Stream providing an encouraging sign that local waterways are responding positively to ongoing environmental efforts. 

The discovery was made during wetland and restoration work led by Wai Connection’s Kirsty Gaddum and Amy Hardy, alongside members of the local Whāngārā community and supported by Whāngārā Farms. For those involved, the finding reinforced the value of continuing restoration planting and protection work across the Waiomoko and wider Pouawa catchment. 

Inanga are highly sensitive to the quality of freshwater environments. They rely on healthy waterways, protected river edges and functioning wetlands to successfully spawn. Finding eggs near a trial planting area was a strong indication that restoration efforts are already helping to improve fish habitat and freshwater conditions. 

But the impact reaches much further than the return of a single species. 

Healthy wetlands play a critical role in filtering sediment, improving water quality and slowing runoff before it reaches rivers and the ocean. At Whitiwhiti, this restoration work has the potential to strengthen the health of the entire catchment, contributing to cleaner freshwater systems and improved coastal environments where the Pouawa River eventually meets the moana near the Tapuwae Marine Reserve. 

Over time, those environmental gains can create wider benefits for the whenua itself - supporting healthier soils, more resilient pasture systems and stronger biodiversity across the landscape. The return of taonga species like inanga is often one of the first visible signs that an ecosystem is beginning to recover. 

For Whāngārā Farms, the discovery also reflects the long-term environmental vision set out through He Rau Ake Ake, the organisation’s 100-year whenua optimisation plan. Within that plan, the Whitiwhiti wetland area - known as Project 146 (T-WR3) - has already been identified as a significant future restoration site.  

Originally scheduled for protection and planting in 2029, the ecological importance of the area and the positive outcomes already being seen may now bring that work forward. 

The proposed project includes fencing, protecting and planting sections of the nine-hectare wetland and riparian area. One option being explored is the creation of strategically planted “islands” of native vegetation along the wetland, allowing native species to regenerate naturally over time and helping restore the wider ecosystem through seed spread and natural growth. 

Importantly, the project also highlights the role people play in environmental restoration. 

The recent wetland event hosted by Whāngārā Farms brought together whānau, environmental specialists and local community members to learn about waterways, fish habitat and restoration opportunities together. It created space for knowledge sharing, connection and collective responsibility for the future of the environment. 

That community involvement is a critical part of long-term restoration success. 

Environmental projects of this scale are not simply about fencing off areas or planting natives. They are about building stronger relationships between people and place, reconnecting communities to waterways and creating a shared understanding that healthy environments contribute directly to healthy communities. 

For farming communities especially, that relationship is deeply connected. Strong waterways support productive landscapes, resilient farming systems and sustainable futures for the next generation. At the same time, restoration projects create opportunities for learning, collaboration and the passing on of knowledge between generations. 

At Whitiwhiti, the discovery of inanga eggs is a reminder that meaningful environmental change often happens gradually. Small signs begin to appear. Waterways begin to recover. Native species return. 

And alongside that, communities strengthen their connection to the whenua and to one another through the shared responsibility of caring for it.
