PumpSwap NZ Media & Press Resources
Data, story angles, and expert commentary for journalists covering New Zealand's energy transition, including the gas supply crunch. We maintain a suburb-level energy cost dataset for NZ.
Ready-Made Story Angles
These angles are grounded in verified public data (MBIE gas statistics, EECA programme rules, NZTA RUC rates) plus PumpSwap NZ pricing data. We can provide supporting data, regional breakdowns, and quotes for any of them.
NZ is running out of natural gas: what the supply crunch means for 270,000 gas-connected homes
Proven and probable gas reserves fell 27% in a single year (1,300 PJ in 2023 to 948 PJ in 2024), a 20-year low, and production is falling faster than forecast (155 PJ in 2023 toward roughly 85 PJ expected in 2026). Household gas prices are rising as retailers rebalance. PumpSwap NZ can provide region-level gas connection context and replacement cost data for gas hot water.
There is no government rebate for hot water heat pumps in NZ, and almost nobody says so plainly
Warmer Kiwi Homes covers insulation and space-heating heat pumps only, not hot water. The real financial lever is bank green home loan top-ups at 0-1% p.a. promotional rates. PumpSwap NZ publishes this honestly and can walk through what each bank actually offers.
The quiet upgrade: most NZ homes heat water with an electric cylinder, and a heat pump cuts that energy use by 65-75%
With residential electricity around 35c/kWh in 2026, hot water is one of the biggest lines on a power bill. PumpSwap NZ has indicative installed pricing by suburb and running-cost comparisons by region.
The South Island has no natural gas network, so its hot water story is different
Reticulated natural gas exists only in the North Island. South Island homes that use gas rely on bottled LPG, which costs more per unit of heat. PumpSwap NZ can break down the regional divide in replacement economics.
EV running costs after the Clean Car Discount: what Road User Charges really add
The Clean Car Discount ended 31 December 2023, and since 1 April 2024 light battery EVs pay Road User Charges of $76 per 1,000km. PumpSwap NZ compares home charging costs with RUC factored in honestly.
No mandated solar feed-in tariff in NZ: buyback rates range 7-12c/kWh by retailer
Solar export buyback is set by retailer plans, not regulation. PumpSwap NZ tracks the published ranges and explains why comparing plans matters as much as panel choice.
