A common question from Canterbury vendors: how much do I have to tell buyers about my property? The legal answer in New Zealand is more nuanced than either extreme of full disclosure or caveat emptor. Here is what the law actually requires.
Unlike some countries, New Zealand does not have a comprehensive mandatory vendor disclosure regime that requires vendors to proactively disclose all known defects before listing. This means you are not legally required to volunteer every problem with your property before a buyer asks. However, this does not mean you can withhold damaging information freely - there are significant legal constraints.
The Real Estate Agents Act 2008 and the Fair Trading Act 1986 both prohibit agents (and vendors by extension) from making false or misleading statements about a property. This means: if your agent's marketing says the roof was replaced in 2020 and it was not, this is a misrepresentation; if you tell a buyer the foundation was earthquake-repaired to a professional standard and you know it was not, this is a misrepresentation; and if your agent says the property has no history of flooding and you know it does, this is a misrepresentation. Misrepresentation can make you liable for the buyer's losses and can make the sale and purchase agreement voidable.
For chattels included in the sale, the Consumer Guarantees Act may require that included items are fit for purpose and of acceptable quality. The standard sale and purchase agreement addresses this by requiring listed operational chattels to be in reasonable working order at settlement. But if you specifically represent a chattel as being in good working order and it is not, you may face additional liability beyond the standard chattels warranty.
The safest approach is transparent disclosure of all known material issues - particularly earthquake repairs, TC land categorisation, any incomplete insurance settlements, known defects in chattels, any council notices, and anything else that a reasonable buyer would want to know before making their decision. Transparency reduces the risk of post-sale disputes, price renegotiations when issues are discovered during due diligence, and potential misrepresentation claims. It also builds buyer trust, which tends to produce better negotiating dynamics. Disclosure conversations should be handled through your agent rather than directly - your agent has professional obligations and communication skills that reduce the risk of informal statements creating unintended representations.
