TARANAKI, 2 September 2026: Methanol producer Methanex plans to indefinitely idle its New Zealand production facilities in Taranaki during the first quarter of 2027. The company says continued declines in domestic natural gas availability have made ongoing production in the country unsustainable.
Methanex has also entered an agreement to sell substantially all of its contracted New Zealand natural-gas entitlements from the first quarter of 2027 through to the end of the decade. The company’s operations have been a significant part of Taranaki industry for more than four decades.
Declining gas availability drives decision
Methanex said the sharp decline in domestic gas availability, combined with the absence of a clear pathway to meaningful new supply, was behind the decision. Natural gas is the principal feedstock used to make methanol, making reliable and competitively priced long-term supply essential to the business.
The move is likely to intensify debate about New Zealand’s energy supply and the future of large industrial operations.
Possible effects on Taranaki jobs and businesses
Methanex has been connected to Taranaki for decades. Alongside its direct workforce, contractors, engineering firms, transport providers and other local businesses are linked to the plants.
As a result, indefinitely idling production could affect not only the company but also the wider Taranaki economy and its supply chain.
Methanex said it would work closely with employees, contractors, suppliers, customers and government stakeholders during the transition. The facilities will be safely idled and preserved, retaining long-term optionality for a restart if future circumstances support one.
A wider question for New Zealand energy policy
The decision comes as concerns continue about declining domestic natural-gas availability and New Zealand’s future energy security.
Reliable and affordable energy is critical for major industrial users. The announcement is therefore not only an industrial development but also an important issue for future energy policy, investment and the country’s ability to retain large-scale industry.
The planned indefinite idling of the facilities during the first quarter of 2027 will mark a significant turning point in Taranaki’s industrial history.
