Water Qualifications Review Outcome

Connexis has reviewed all of the water treatment-based qualifications. While there were no substantive changes to the outcome of the qualifications, there is now a slightly different suite of qualifications aimed at future-proofing the qualifications pathway in the long term.


The result of the review is that the following qualifications have been approved and listed at NZQA:

  • NZC in Water Treatment (Small Scale Systems) (Level 3) with strands in Drinking-water and Wastewater 
  • NZC in Drinking-water Treatment (Level 4) with an optional strand in Multistage Processes  – the programme behind the Level 4 programmes have not changed so no learner/industry will not be disadvantaged. New programmes have also been approved.
  • NZC in Wastewater Treatment (Level 4) with an optional strand in Multistage Processes.
  • NZD in Drinking-water Treatment (Level 5) – the original Diploma qualifications have yet to be released so the new Diploma qualifications will now be used. The proposed programmes have not changed. New programmes have also been approved.
  • NZD in Wastewater Treatment (Level 5).

The following qualifications have now expired:

  • NZC in Water Treatment (Level 3) with strands in Drinking-water and Wastewater  – incorporated into the L3 in Small Scale Systems.
  • NZD in Water Treatment (Level 5) with strands in Drinking-water and Wastewater – replaced by two separate Diploma qualifications.
  • NZC in Water Treatment (Level 4) with strands in Drinking-water, Wastewater, Drinking water Multistage Processes, Wastewater Multistage Processes – replaced with two separate L4 qualifications.
  • NZD in Drinking-water Assessment (Level 5) – a more fit for purpose qualification to be developed.

The following qualifications are to be developed:

  • NZC in Drinking-water Supply (Assessment) (Level 5) – this is a replacement for the previous diploma qualification that has never been released.
  • NZC in Onsite Wastewater Management System Design (Level 5) – this is a replacement for the older NC qualification that had expired a couple of years ago, however, the unit's standards are still being used by the industry.
