WHATUMA AND THE TUKITUKI CATCHMENT - Healthier water in the Tukituki catchment

Check out our more detailed publication about Whatuma here

What do we want to fix?


During summer, low flows and higher temperatures mean that toxic algae can form in the Tukituki river. This is a risk for humans and dogs and affects the recreational aspect of the lower reaches of the river. Better water quality can also help the trout fishery.

What do we want to do?

We want to develop and environmental enhancement plan for river and stream edges, lake and wetlands [riparian],and enhance the biodiversity.

We want to continue to work to improve the water quality in the Tukituki catchment.  The Tukituki Plan is in place and farm environment management plans include fencing off waterways and planting streams edges, as well as land use management. 

Lake Whatuma is an important lake for water fowl, especially the largest NZ population of the very endangered native Bittern.  The water quality in this very shallow lake is affected by nutrients coming off the land and also the large numbers of water fowl, so algal blooms can result.  Reducing nutrient input will help.  HBRC will continue controlling willow along the margins to protect the swamp habitats while essential predator control by landowners and water fowl hunters will continue to be supported by HBRC.
