Parliament has passed legislation establishing New Zealand's first regulatory framework for offshore wind, solar, wave and tidal energy developments in territorial waters.
The Offshore Renewable Energy Bill, which passed on 30 June, creates a two-stage permitting system covering feasibility studies through to commercial operation. Energy Minister Simeon Brown announced the passage of the legislation.
Permitting framework
The regime introduces a two-stage process: developers first obtain feasibility permits for site investigation, then apply for commercial permits covering construction and operation.
The legislation allows safety zones around developments and requires infrastructure to be decommissioned when no longer in use. Provisions in the Bill enable selection of developments that best serve national interests and manage risks to the Crown and public.
The first tender round for permits is expected in the coming months.
South Taranaki potential
A single large project in the South Taranaki Bight could potentially generate enough electricity for more than 650,000 homes.
Wind conditions off the South Taranaki coast are comparable to the North Sea, the world's most productive offshore wind region. Steadier offshore winds are expected to allow turbines to run at higher capacity than land-based installations.
Filling a regulatory gap
No regulatory framework previously existed for offshore renewable energy developments, creating uncertainty for potential developers seeking to establish projects in New Zealand waters.
The legislation arrives as New Zealand's renewable electricity generation reached a record 96.4% in the final quarter of 2025.
What comes next
With the permitting framework now in place, developers can begin preparing applications for the initial tender round. The two-stage process means successful feasibility permit holders will conduct site investigations before applying for commercial permits to build and operate facilities.
