What should I check when buying a house that might leak?
Common question · Leaky Buildings & Weathertightness · New Zealand · 23 October 2026
General information from Lawmateanz
Before buying a home in New Zealand, especially one with monolithic cladding built in the 1990s or 2000s, get a pre-purchase inspection from a qualified building surveyor, including invasive moisture testing if there are risk factors.
Check the council's records through a Land Information Memorandum (LIM), including whether a code compliance certificate was issued for building work.
Ask whether there's been a weathertightness claim or repair, and get copies of any reports.
Make your agreement conditional on a satisfactory building report and LIM, and have a property lawyer review it before you sign.
