What actually exists in Waikato→The energy picture in Waikato
Hamilton and much of the Waikato are on the North Island gas network, though most homes still heat water electrically. With NZ gas production falling (about 155 PJ in 2023 to an expected ~85 PJ in 2026), gas hot water is getting more expensive to run, and end-of-life replacement with a hot water heat pump usually pays back well here.
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 Pirongia 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.
