If we are wrong, we would rather know than not know.

Why we have one

Most figures on Custailo are copied from a published source by a person, and the rest are labelled estimates until they are. People mis-read tables, miss a footnote, and fail to notice when a source updates. Rules change on a Tuesday with no announcement. Over a site of this size, being wrong occasionally is not a risk. It is a certainty.

The only real question is what happens next. A site that quietly edits the number and moves on has asked you to trust it and given you no way to check. So we aim to do the opposite: make the fix, date it, and leave it visible on the page rather than quietly editing the number away.

How to tell us

Email hello@custailo.com. Put the word correction somewhere in the subject line and it gets read first.

What helps, roughly in order:

• Which page, and which figure or sentence. A link and a quote is ideal.
• What you think it should say.
• A source, if you have one. A link to the official page is the fastest possible route to a fix. If you do not have one, send it anyway. Finding the source is our job, not yours.

You do not need to be polite, certain, or an expert. "I think the rent number for Hamilton is too low" is a perfectly good correction. So is "this paragraph is confusing": a page that is technically correct and impossible to understand is also wrong, just in a way that is harder to spot.

The four kinds of fix

Not every change is a correction, and calling everything one would make the label meaningless.

• Correction. We published something factually wrong. The page carries a dated correction note and the note stays there permanently.
• Update. We were right, and then the world changed: a fee rose, a rule was replaced. The figure changes and the "checked" date changes. This is normal maintenance, not a correction, and is not marked as one.
• Clarification. The facts were right but the wording misled. We rewrite it, and note that we did, because a reader who acted on the old wording deserves to know it has moved.
• Typo. Spelling, a broken link, a formatting mess. Fixed without a note. If a typo changed a number's meaning, it is not a typo. It is a correction.

How a corrected page is marked

A corrected page carries a dated note near the figure or at the foot of the page, saying what it used to say and what it says now. Plainly, in the same words we would use to a friend:

We do not delete the old figure and pretend it was never there. We do not date-stamp the page as freshly updated to hide that it was wrong for a while. If a correction is serious enough that people may have acted on the wrong number, it goes in the next email to the list as well as on the page.

What we cannot do

Two limits, and they are the same limits that run through the whole site.

We cannot answer questions about your own case. A correction tells us a published fact is wrong. "Does this mean I qualify?" is a different question, and one only a licensed immigration adviser or a lawyer may answer. If you ask it, we will say so and point you to the IAA register, not because we are being unhelpful, but because in New Zealand it is not ours to answer.

We cannot correct someone else's site. If an official source is itself wrong or out of date, we will say on the page that the source and reality appear to disagree, and we will show both. What we will not do is quietly substitute our own number for the official one.

If you disagree with the outcome

Sometimes we will check a correction and conclude the page was right, or that two credible sources disagree and both should be shown. When that happens we will write back and explain the reasoning and show you the source we relied on, rather than just saying no.

If you still think we are wrong, say so again with whatever you have. We would rather have the argument than leave a wrong number up.
