NZ's natural gas supply running out faster than thought

The country's natural gas supply is running out faster than previously thought.
The Ministry of Business, Innovation and Employment said previous forecasts showed annual gas production falling below 100 petajoules (PJ) by 2029, but revised forecasts indicated that level would be reached by next year.
A petajoule or PJ is a unit measurement of energy use commonly used for large-scale energy use, with one petajoule equal to one million billion joules.
MBIE also said as of January this year, natural gas reserves were down 27 percent compared to last year - also falling faster than previously estimated.
"In 2024, natural gas proven plus probable (2P) reserves reduced from 1300 PJ to 948 PJ," MBIE head of data service delivery," Karlene Tipler said.
"The reduction in natural gas reserves is largely driven by field operators reducing their estimates of gas readily extractable in the ground by 234 PJ."
MBIE said contingent gas reserves, or gas that existed in the ground but could not be extracted for various reasons such as economic or technical, increased by 184 PJ or 10 percent on last year.
"Some of this increase can be attributed to natural gas reserves being downgraded to contingent resources," Tipler said.
"A significant contributor to this is Pohokura field, which included a large volume of contingent gas which had previously not been reported."
Tipler said some contingent gas may have the potential to be upgraded to 2P if there were changes to economic or technical conditions.
Resources Minister Shane Jones said the decline in gas reserves was a "stark reminder" of why the government was seeking greater investment in exploration and production.
"New Zealand needs a secure supply of affordable and reliable gas for industry to continue and for Kiwis to keep the lights on," Jones said.
"A 27 percent year-on-year decline in our natural gas reserves is further proof that the Coalition Government has made the right decisions in overturning the oil and gas ban, and is willing to become a cornerstone investor in gas production," he said.
As part of Budget 2025, thegGovernment announced $200 million over four years for co-investment in new domestic gas field developments.

Chair refuses to apologise, rejects use of ‘kia ora' in council email
Environment Southland has eight catchment committees across the region. Photo: ODT/Supplied A chair of a southern council group is unrepentant about his behaviour at a recent meeting, which was dubbed "disrespectful" by a council leader. Mataura catchment liaison committee chair Hugh Gardyne has also rejected the use of 'kia ora' in an email reprimanding him for his actions. The committee Gardyne oversees is one of eight in the region that supports Environment Southland with local river work. In May, Gardyne gave a blunt presentation to councillors, alleging catchment management was in "a state of paralysis" under the watch of the council chief executive and that communication was ineffective with the general manager in charge. He was shut down at the end of his talk, when he mentioned an abatement notice later revealed to be one [ issued by Environment Southland against itself]. A letter from Environment Southland chair Nicol Horrell on 28 May warned Gardyne of his behaviour, saying parts of his presentation were factually incorrect and disrespectful. "My intention is both to correct your understanding of the facts, and to inform you that councillors will not tolerate any criticism levelled at staff in public meetings or disrespectful behaviour," Horrell wrote. He added it was incorrect to suggest catchment work was in a state of paralysis and accused Gardyne of not having all the facts. "I would be interested to know from where you are getting your information." The letter ended with a suggestion that Gardyne apologise to the chief executive and manager in question, but Gardyne has defended his actions, saying his criticism was about questioning professional ability. "It doesn't, in my opinion, deserve a response or an apology." Hugh Gardyne chairs the Mataura catchment liaison committee, which helps Environment Southland with river management. Photo: ODT/Supplied Gardyne said he would speak at council again in the future and the response from the general manager had been "great", following the presentation. Separately, he also took exception with the use of 'kia ora' in the email sent by Horrell, which delivered the reprimanding letter. Gardyne requested he instead be addressed with 'hello' or 'dear'. Horrell told Local Democracy Reporting using the te reo Māori greeting was commonplace and he didn't think its use would be Gardyne's biggest issue. "I would have thought that that's almost a wee bit racist." In a letter back to Horrell, Gardyne doubled down on perceived issues with river management and questioned whether the chair's concerns were shared by other members. Environment Southland oversees eight catchment liaison committees, which help the council develop annual maintenance programmes and budgets, as well as provide a local point of contact. Gardyne has been involved with the Mataura group since the early 1990s. Last month, the council said it was working to improve communication with its catchment committees.
