Motueka bore water quality survey

Water sampling for the Motueka/Riwaka groundwater quality survey has been completed. A report detailing the findings from the sampling is being produced and will be made available in the next few months.

In October and November 2019 we tested bore water quality across the Motueka/Riwaka Plains.

Our aim was to identify:

  • Any health risks to water users
  • Any changes from previous results in the area.


What are the issues with water sourced from bores?
Why is testing important?

About this project

Motueka has an estimated 2000 private domestic bore water takes Local bores source water from rivers and ground aquifers. These are fed by rainfall which soaks in through the land, and there are many potential sources of contamination. As the water is not piped through a council treatment plant, there is no testing or treatment to ensure water quality meets national standards.

Approximately one-third of the houses in Motueka are connected to the Tasman District Council water supply. This makes Motueka the largest town in New Zealand that doesn’t have a fully reticulated (networked) supply.

Will the results of this survey mean I have to join the Tasman District Council reticulated water supply?
