Big changes are on the way for the plumbing industry in New Zealand, with new self-certification rules set to streamline how qualified professionals sign off their own work. We’re excited to support this change as it promises greater efficiency while still maintaining high standards!
Exciting news for plumbers and drainlayers! 🙌
The government has expanded the proposed self-certification scheme to include more routine plumbing and drainlaying work, including some commercial jobs.
The feedback we, and members, gave throughout the Bill's consultation process is reflected in today's announcement.
Now in scope for self-certification:
✅ Septic tanks & pumped systems
✅ Stormwater retention & greywater systems
✅ Certain commercial jobs
More complex work will still require council consent and inspection.
"The Minister has listened to industry feedback and worked collaboratively with the sector to ensure the new scheme is practical and effective," says Greg Wallace, CEO of Master Plumbers and Masterlink.
"The scheme strikes a sensible balance between maintaining standards and enabling efficiency, and will be well received by plumbers, drainlayers, and consumers alike."
The Bill is progressing through Parliament, with rollout expected later this year.
BE AMONGST THE FIRST!
