What actually exists in Auckland→The energy picture in Auckland
Auckland sits on the North Island reticulated gas network, and roughly a third of homes have a gas connection. NZ gas production is declining fast (reserves fell 27% in a single year to a 20-year low), which is pushing household gas prices up. No ban is legislated, but replacing gas hot water with a hot water heat pump at end-of-life is increasingly the cheaper long-run choice.
New Zealand has no gas ban, but the supply picture is shifting: proven gas reserves fell 27% in a single year to a 20-year low, and production is falling faster than forecast. For Tawharanui households with gas hot water, the practical takeaway is to plan ahead. Keep using and repairing your current system, but when it reaches end-of-life, replacing it with a hot water heat pump rather than another gas unit avoids locking in 10+ more years of exposure to rising gas prices.
