Editorial Standards

Who produces PumpSwap NZ content

PumpSwap NZ content is produced by the PumpSwap Editorial team, an in-house group that researches home electrification costs across New Zealand. The team is not a single bylined author. Articles are a collective product, researched against primary sources and reviewed before publication. We do not publish content under invented personas or fabricated credentials.

Where a claim depends on licensed-trade knowledge (electrical regulations, switchboard work, installation practice), we describe what New Zealand regulation actually requires and link to the relevant authority. We do not present PumpSwap as an electrical contractor or plumbing business. Electrical work on EV chargers, hot water heat pumps, and solar must be carried out by an EWRB-registered electrician, and hot water cylinder plumbing by a certifying plumber.

How we research

Every figure on PumpSwap NZ traces to one of three source types:

• Government and agency data: EECA (Warmer Kiwi Homes programme rules), MBIE (gas supply and demand statistics), and NZTA (Road User Charges for EVs).
• Published lender and retailer terms: bank green home loan terms (ANZ, ASB, BNZ, Westpac) and electricity retailer solar buyback plans, checked against the providers' own pages.
• Manufacturer and retail data: official brand specifications and current New Zealand pricing, cross-checked against NZ retail and installer pages.

How we verify pricing

Installed cost ranges are published as indicative ranges, never quotes. They are built from published NZ supply-and-install bundle pricing and installer cost guides, and refined with real quote data passing through the PumpSwap platform plus anonymous community price submissions as they accumulate. Outliers above the 99th percentile are excluded. Suburb-level variation reflects metro versus regional installer competition and local housing stock, not guesswork.

Vehicle prices, charger hardware prices, and electricity rates are reviewed against current sources at least monthly. The most recent review date is shown on every cost page and guide.

How often we update

Cost pages, the cost index, and the statistics dashboard are reviewed monthly. Guides are reviewed when the underlying data materially changes (an RUC rate change, a fuel price shift, a new vehicle launch, a bank changing its green loan terms) and carry a visible "last reviewed" date. When a figure changes, we update it across every page that references it rather than letting stale numbers persist.

Independence

PumpSwap NZ is not affiliated with any vehicle manufacturer, charger brand, installer, or energy retailer. We do not accept payment to rank or recommend any brand. PumpSwap earns revenue by charging installers a flat fee per matched lead, never a commission on what a homeowner spends. Brand comparisons reflect specifications and market pricing, not commercial relationships. And because it matters in NZ: there are no government rebates for hot water heat pumps here, and we will never imply otherwise to make a sale look better.

Corrections

If you find a figure you believe is wrong, email editorial@pumpswap.com.au with the page and the source you think is more accurate. We correct verified errors promptly and update the review date on the affected pages.

Not financial or trade advice

PumpSwap NZ content is general information only. Loan, running-cost, and total-cost-of-ownership calculations depend on individual circumstances. Check green home loan terms with your bank, and use an EWRB-registered electrician for electrical work and a certifying plumber for cylinder plumbing.
