New rules restricting lead plumbing products will ensure new homes and buildings are fitted with modern plumbing products that protect the quality of drinking water, says Minister for Building and Construction, Chris Penk.
“The quality of the buildings where we live, work and play can have a significant impact on our wellbeing, and there is growing evidence that even trace amounts of lead exposure can be harmful over time,” Mr Penk says.
“International health advice shows that removing lead from plumbing products entirely is the most effective way to reduce the risk of exposure.”
From tomorrow, all pipes, fittings, valves and tapware that come into contact with drinking water must be lead-free for new buildings or renovations. Under the new rules, tapware must also be resistant to dezincification to help maintain water quality over time.
“That means designers and tradies will need to check that products specified in a building consent and those installed meet the updated requirements and confirm early with suppliers that compliant products are available, so they don’t get caught short,” said Mr Penk.
“The move to lead-free plumbing products has been well signalled. In 2022, plans were announced to tighten the amount of lead permitted in plumbing products used for drinking water, alongside a transition period to give the industry time to prepare before the updated guidance comes into effect from 2 May.
“We have received positive feedback from plumbers, other trades, and suppliers, which suggests the industry is well placed to transition. It’s estimated any additional cost from using lead-free plumbing products will be negligible.
“This update sets a clear, modern standard and gives New Zealanders confidence in the safety of their drinking water. It is a sensible, preventative step that will benefit the wellbeing of Kiwis over the long term.”
More information on lead-free plumbing and dezincification requirements can be found on the MBIE website.
