Unit title guidance from Quay Law

Weathertightness and Remediation in Auckland Unit Titles

Ian Mellett, Barrister and Solicitor, Quay Law

Auckland’s experience with leaky buildings has shaped the way many buyers approach apartments and townhouses. Weathertightness failure can be costly to repair, and in a unit title development that cost is shared by every owner.

Auckland's Leaky Building Legacy

A significant number of Auckland buildings constructed during the 1990s and early 2000s were affected by weathertightness failure, caused by a combination of building methods, materials and design. Many have since been remediated. Others have issues that are still being investigated, are under repair or have not yet come to light.

A building from this period is not necessarily affected, and a remediated building can be a sound purchase. The key is knowing which category a building falls into.

Disclosure of Weathertightness Issues

Since May 2023, the pre contract disclosure statement must include information about weathertightness issues affecting the development that are known to the body corporate. This applies whether or not the issues have been remediated and whether or not legal proceedings have been brought.

The minutes, remediation reports and financial statements included in the disclosure bundle often provide further detail.

Remediation Projects and Their Cost

Remediation may involve repairs to specific areas or a full reclad of the building. It is commonly funded through special levies, and in some cases through borrowing by the body corporate or staged payments over time. Owners may need to vacate during the work.

Buying Into a Building Under or After Remediation

If a building has been remediated, we recommend obtaining details of the work, the consents and code compliance certificates, and any warranties. If remediation is underway or planned, the key questions are how much remains to be paid, by whom and when.

Signs to Look For

  • References to leaks, moisture readings or cladding in the minutes.
  • Remediation or building reports commissioned in recent years.
  • Special levies proposed or recently raised.
  • Notices or records on the council property file.
  • Lender or insurer concerns about the building.

Selling in an Affected Building

Sellers must disclose known weathertightness issues accurately. Clear, complete disclosure, supported by records of any remediation, helps buyers and lenders assess the building with confidence.
