Rebates and Financing for Stiebel Eltron in Tawhiwhi
None exist in New Zealand

What actually exists in Taranaki→The energy picture in Taranaki
Taranaki is the home of NZ gas production and has the country's highest household gas connection rate. That cuts both ways: as the fields decline (reserves are at a 20-year low), local households face the same rising gas prices as everyone else. A hot water heat pump typically cuts water-heating energy use by 60-75% compared with a gas or electric cylinder.
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 Tawhiwhi 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.
