What has the amendment changed?

NZS 5266

The currently cited version, NZS 5266 (Int):2012 changes to:

NZS 5266:2014 Safety of gas appliances

• You can choose to use the new version of the standard from 13 November 2025.
• All new endorsements begun after 12 November 2026 need to comply with the new version of the standard.
• If you work on an endorsement after 13 November 2025 and choose to use the old version of the standard, you must have that endorsement issued by 12 November 2026.
• If you had already started work on an endorsement before 13 November 2025, you can choose to keep using the old version of the standard up until the point that the endorsement work is complete. Theres no time limit on completion for using the old standard in this case.

AS/NZS 5601.2

If you undertake Section 2 inspections on imported installations, the citation of AS/NZS 5601.2 has also been updated to:

• AS/NZS 5601.2: 2020 Gas installations—Part 2: LP Gas installations in caravans and boats for non-propulsive purposes, including Amendments 1 and 2.

Clause changes

The Government has made some changes to AS/NZS 5601.2 in citation:

1. Delete clause 2.13.2
2. In clause 2.13.3.3(a), replace “2.75” with “3.5”
3. In clause 5.2.9, first paragraph, delete “compression joints, union joints,”
4. Delete section 10

What these changes mean for industry:

• This allows jointing compound to be applied to a compression joint.
• This allows European and north American appliances to run at the slightly higher pressures they need.
• This allows jointing compound to be applied to the face of a copper flare, olive, and galvinised steel mac union. This jointing compound can still not be used to compensate for ill-fitting joints.
• A gas compliance plate is not required in New Zealand. In New Zealand a person who performs gasfitting work is required to issue a CoC for general and high-risk work, a GSC for all gasfitting work, and place a record of the CoC on the WorkSafe Electricity and Gas High Risk Database for all high-risk work.

In all cases, if you choose to apply jointing compound, it must be a proper jointing compound that is non-setting. A setting thread sealant or silicone cannot be used as the standard does not allow it.

Actions for approved practitioners
