What Australia is doing
Australia and New Zealand share the standard that rules out plugging solar into a socket, so both countries have to change it or work around it.
For New Zealand, see the tracker: not yet legal, expected around mid-2027, no date set.
Where Australia stands
Plug-in solar isn't allowed in Australia. AS/NZS 4777.1, the joint installation standard, requires fixed wiring and rules out three-pin plugs on both sides of the Tasman (RenewEconomy).
On 11 September 2026 the Energy and Climate Change Ministerial Council, which New Zealand's energy minister sits on, "agreed to explore pathways to support the safe deployment of plug-in consumer energy resource (CER) devices in Australia", with a report back on next steps this year (the communique). We found no draft Australian standard.
Why it matters here
- The same standard. If the joint committee changes AS/NZS 4777.1, both countries move; New Zealand's review says it can enable plug-in solar before a full standard is finished.
- The same shops. Bunnings, Harvey Norman and the battery brands sell on both sides, and a bigger joint market brings more kits.
- New Zealand looks set to go first. The government has agreed to legalise it; Australia has agreed to explore it.
National says it has "teamed up with Australia on shared rules". We haven't found a government document that confirms it.
