General information only

Pages on this site describe how borer and other wood-boring insects behave in New Zealand buildings, what inspections and treatments involve and what they tend to cost. The facts are checked against the sources listed on each page, but they describe typical situations, and a particular house can differ.

Not building or purchasing advice

Nothing on this site is a building inspection, a structural assessment or advice on whether to buy a property, what to offer or how to word a sale and purchase agreement. For those decisions use a building inspector, a builder or engineer, and your lawyer.

Products and chemicals

Where products are mentioned they are described by type. Always follow the label of any insecticide or timber preservative, which is the legal instruction for its use in New Zealand.
