A Practical Guide to NZS 3902:2004 -Housing, Alterations and Small Buildings

NZS 3902:2004 is a New Zealand Standard written specifically for minor works, maintenance, and repair projects. It is designed to be used for projects of a value over $30,000, but its clear structure makes it equally valuable for lower-value work - because using a proper contract, regardless of project size, sets clear expectations for both parties and reduces the risk of disputes later.

The contract is derived from NZS 3910, which means it is grounded in industry best practice while being written in plain English. One party - the Contractor or Builder - agrees to perform works of a minor nature or carry out maintenance or repair work for the other party - the Owner or Principal.
