A new micro-credential has been developed for backflow device testing and was submitted to NZQA for approval in December 2025.

This project has transitioned to the Construction and Specialist Trade Industry Skills Board to respond to any requests for further information and update stakeholders

Why is this important?

Drinking water protection with the use of backflow water devices is vital to manage the water supply. Plumbers, those involved in the water supply industry and fire systems engineers are required to test backflow water devices to ensure they are working correctly and protect the clean water supply from contamination.

This micro-credential will allow operators to show competence in testing by obtaining the skills and knowledge required to test a device.
