New Zealand faces critical questions about its future energy security after proven and probable natural gas reserves dropped 23% to 731 petajoules, according to government data released for the year.
Offshore Exploration Permits and the Kaheru Basin Outlook
EnZed Energy secured a permit to undertake a staged exploration programme targeting the Kaheru prospect, situated within a basin described by executive chairman Neil Young as one of the most extensively studied petroleum provinces in the Southern Hemisphere. According to EnZed Energy, the initial work phase will focus on technical evaluation and interpretation of existing geological and geophysical information. Under the permit terms, the company plans to study existing seismic data to better understand the offshore area’s potential before deciding on future drilling steps.
Declining Domestic Gas Reserves Drive Energy Policy Shifts
New Zealand’s natural gas reserves have fallen to their lowest level since records began more than two decades ago, according to government figures. Jones stated that the depletion underlines the urgent need to understand remaining resource potential to support future economic prosperity. To counter this trend, the coalition Government repealed an oil and gas exploration ban in July 2025, removing a restriction that had been put in place by the preceding Labour-led Government in 2018. The last major offshore natural gas discovery in the country was the Pohokura field off the Taranaki coast in 2000.
Did You Know?
The Pohokura field, discovered off the Taranaki coast in 2000, remains the last major offshore natural gas find in New Zealand. Domestic production from aging fields has steadily matured since then, leading to the current push for new offshore basin evaluations.
Commercial Realities and Joint Venture Prospects
While exploration offers a potential pathway to bolster long-term energy security and reduce reliance on imported fuels, industry leaders emphasize that discovery is not guaranteed. EnZed Energy executive chairman Neil Young noted that any future drilling programme will likely be conducted through a joint venture with multiple oil and gas companies, adhering to standard industry practice. Successful commercial development could support reliable electricity generation and preserve industrial production in key sectors like fertilizer, though companies must first navigate rigorous technical evaluations of the basin.
Frequently Asked Questions
Why did New Zealand experience a power price spike recently?
According to energy sector reports, price spikes were driven by a combination of a 23% drop in proven and probable natural gas reserves, low lake levels impacting hydro generation, and calm wind conditions limiting wind power output.
Who holds the new permit for the Kaheru prospect?
EnZed Energy holds the permit to undertake the staged exploration programme, which begins with technical evaluations of existing seismic data and geological studies.
When was the offshore exploration ban lifted?
The coalition Government repealed the offshore oil and gas exploration ban in July 2025, reversing a policy introduced by the Labour-led Government in 2018.
