There is no battery rebate in New Zealand
No government scheme subsidises home batteries here. What does exist: bank green home loans from 0-1% promo rates, and Tesla's time-limited "Next Million Powerwall Rebate" promo ($850 off per Powerwall 3, max $1,700 - a manufacturer promo, not a government one). The good news: battery prices are falling 10-15% a year, and every kWh you store and use at home is worth roughly three times what a retailer pays you for exported solar.
