The New Zealand government has granted Australian firm EnZed Energy a 12-year offshore petroleum exploration permit in the Taranaki Basin, the first such permit issued since the offshore oil and gas exploration ban was lifted on 31 July (RNZ).

Resources Minister Shane Jones announced the permit in a statement, calling it a "major milestone." The permit covers a 546 square kilometre area east of the Kupe gas field and includes the Kaheru prospect, which Jones described as a promising exploration target (RNZ).

EnZed Energy is expected to carry out staged exploration, beginning with a study of existing seismic data and geological work rather than immediate drilling. The permit area sits in a basin with established hydrocarbon infrastructure, adjacent to the producing Kupe field.

Jones said previous policy settings had discouraged investment in the offshore oil and gas sector. He stated that proven and probable gas reserves fell 23 percent in 2025 to the lowest level since records began, framing the permit as part of the government's response to declining gas supply (RNZ).

The grant follows engagement between the Ministry of Business, Innovation and Employment (MBIE) and the company. MBIE held a meeting with EnZed Energy, with a briefing prepared on 27 March 2026 ahead of a meeting scheduled for 30 March 2026 (MBIE). Jones also travelled to Taranaki in late February, with a briefing prepared on 20 February 2026 for a trip on 24 February 2026 (MBIE).

EnZed Energy's application for the offshore Taranaki Basin permit had no competing bids (RNZ). The block was not subject to a contested allocation process.

The permit is the first concrete output from the government's decision to reverse the 2018-era ban on new offshore exploration acreage, a policy change the coalition has pursued since taking office. The 12-year term gives EnZed Energy a substantial window to progress from desktop studies through to drilling decisions, consistent with the typical lifecycle of offshore petroleum exploration in New Zealand's regulatory regime.

Jones's framing of the 23 percent decline in proven and probable reserves positions the permit within a supply-security argument rather than a purely economic one. Gas reserves data is tracked by MBIE and is closely watched by industrial users and electricity generators, given the role of natural gas in peaking generation and feedstock for petrochemical production at Kapuni and Waitara Valley. The drop to the lowest level since records began underscores the tension between the government's pro-development resources agenda and the lead times inherent in offshore exploration, where a discovery today would take years to bring into production.

The Kaheru prospect itself is not a new geological feature in the basin's inventory. Its inclusion in a granted permit signals that the acreage was considered prospective enough to attract an application, though the absence of competing bids tempers any read on broader industry appetite. International oil and gas majors have largely exited New Zealand's offshore basins over the past decade, leaving smaller independents like EnZed Energy as the primary actors in new exploration.

The staged work programme, beginning with seismic reprocessing and geological studies rather than well commitments, means the immediate environmental and operational footprint of the permit is limited. Under the Crown Minerals Act framework, a permit holder must meet specified minimum work programme obligations, and further activity, including any drilling, would require separate consents under the Resource Management Act and the Exclusive Economic Zone and Continental Shelf Act.

For the Taranaki region, where the oil and gas sector remains a component of the local economy, the permit signals that the regulatory door is open. Whether further applications follow, and whether the Kaheru prospect progresses beyond desktop studies, will be the practical test of whether the lifting of the ban translates into sustained investment.
