Standards and corrections

How we keep our tools and articles accurate, fair and honest.

Our tools

1. Official sources first. Every rule comes from an official source such as Inland Revenue, Employment New Zealand, Tenancy Services, Stats NZ or the Reserve Bank. The source is linked on the tool page.
2. Tested before it goes live. We check each calculator against worked examples, including edge cases, and compare the results with the official rules.
3. Dated. Each tool shows when it was last checked. Rates and dates change, so treat an old date as a reason to check the source.
4. Honest about limits. Each tool says who it is for and what it does not cover. Where a case is complicated we point you to a person: the agency, Community Law or Citizens Advice.
5. Updated when rules change. We review the tools when a rule or rate changes and each April when the tax year rolls over.
6. Private. Calculators run in your browser. What you type stays on your device.

Our articles

Accuracy and fairness. We summarise reporting from credible New Zealand outlets and always link to the original. If someone is criticised in a story, we include their response or note that they were asked.

Non-partisan. We do not take sides between political parties.

Photos. We only use freely licensed photos and credit the photographer and licence under each one.

Sourced. Every story links to the source it draws on, so you can check it yourself. See how we make things.

Money and independence

Ads, sponsored stories and partner links are always labelled and never change a result or a story. The full list is on our how we stay free page.

Corrections

If we get something wrong we fix it and say so. When a tool is corrected, we note the change and the date on that tool page. When a story is corrected, we note it on the story.

To ask for a correction, email [email protected] with the page address and what looks wrong, ideally with the official source that shows it. You can also use "Not quite" under any tool.
