Minister for Regulation David Seymour has published a review containing 15 recommendations to streamline solar uptake in New Zealand, including legalising plug-in solar panels that are currently banned over electricity and fire safety concerns.

The review, released by the Ministry for Regulation on 30 July 2026, covers residential and small-to-medium-scale solar installations, encompassing rooftop, ground-mounted, and plug-in systems. The Ministry estimates the recommendations could deliver net benefits of between $28 million and $50 million over 10 years, and expects all 15 could be implemented within 18 months. Initial advice on review options is due later in 2026. Ministry for Regulation

A typical residential solar system costs between $8,500 and $11,500, according to the Ministry for Regulation. Seymour has said that most New Zealand households could save more than $1,000 a year on electricity by adopting solar, and that installation currently takes months. Beehive.govt.nz

The plug-in solar recommendation is likely to draw the most attention. Plug-in solar panels, which plug directly into a standard household socket, are illegal in New Zealand due to concerns over electricity and fire risks. Seymour noted that in Australia, consumers can buy them at Kmart and use them without restriction. RNZ

The electrification advocacy group Rewiring Aotearoa welcomed the 15 recommendations. Its policy director, Dave Karl, backed the package. Heath Coleman, co-founder of solar industry company Future Energy, also features in the industry response. Consumer NZ's power switch manager, Paul Fuge, said solar installations typically take less than a decade to pay themselves back. RNZ

The review builds on an earlier RNZ report that the Ministry for Regulation had recommended legalising plug-in solar. The broader review was first signalled in a Beehive press release titled "Solar panel installation to be done at lightspeed," published on 7 May 2026, when the review was formally launched. Seymour also announced a separate "Solar on schools" initiative in 2026, stating that schools will save money, have greater energy security, and reduce energy bills. Beehive.govt.nz

The 18-month implementation timeline is notable against the backdrop of a sector where installation delays are a recurring complaint. Seymour's framing, that installation "currently takes months," signals that the review is as much about regulatory friction as it is about upfront cost. The $28 million to $50 million net benefit estimate, while modest in fiscal terms, is concentrated in household-level savings rather than government expenditure, which aligns with ACT's long-standing preference for consumer-side deregulation over subsidy.

The plug-in solar proposal is the most politically charged element. The ban rests on genuine electrical safety grounds, and any liberalisation will need to satisfy WorkSafe and electrical code requirements. Australia's more permissive approach, which Seymour cited, operates under different regulatory architecture. Translating that model to New Zealand's framework will require ECP-compliant product standards and likely some form of installer or consumer certification, even if the full compliance burden is lighter than the current hard prohibition.

For the solar industry, the recommendations arrive at a point when payback periods are already contracting. Consumer NZ's Fuge putting the typical payback at under a decade gives the review a tailwind: the economics are improving independently of the regulatory changes, which means the 15 recommendations could compress timelines further rather than rescue an unviable proposition. Rewiring Aotearoa's endorsement, from an advocacy group focused on electrification rather than industry interests, suggests the package has drawn support beyond the usual commercial voices.

What remains to be seen is how quickly Cabinet adopts the recommendations and which agencies take the lead on implementation. The Ministry for Regulation's expectation that all 15 can be in place within 18 months is an internal estimate, not a Cabinet commitment. The review covers a mix of building consent, electrical safety, and retail market settings, which means multiple ministers and agencies will need to coordinate. The "Solar on schools" initiative, while separate, signals that the government is thinking about solar uptake across the public estate as well as the private market.
