How to Get a Building Warrant of Fitness in New Zealand

How to Get a Building Warrant of Fitness in New Zealand

Keeping your building safe, compliant, and functional is more than just good management, it’s a legal requirement. For New Zealand building owners, understanding how to get a Building Warrant of Fitness (BWoF) is an important part of ensuring that every system in the building meets safety and performance standards under the Building Act 2004.

In this guide, we’ll explain what a Building Warrant of Fitness (BWoF) is, who needs one, the steps to get your certificate, and how electrical maintenance plays a key role in keeping your building safe and compliant.

What Is a Building Warrant of Fitness (BWoF)?

A Building Warrant of Fitness is an annual certificate that confirms a building’s specified systems, such as fire alarms, sprinklers, lifts, ventilation systems, and emergency lights, have been properly inspected, tested, and maintained in the previous 12 months.

It serves as proof that the building owner has met their obligations under the Building Act 2004 and that the building is safe for occupants and visitors.

The BWoF must:

  • Be issued and signed by the building owner each year.
  • Confirm that all systems in the building have been checked by Independent Qualified Persons (IQPs).
  • Be displayed publicly in the building’s main entrance.
  • Be sent to the local council along with supporting documentation.


This annual BWoF certificate assures tenants, visitors, and authorities that the building’s specified systems are functioning as designed and that the property has fully complied with safety regulations.

Who Needs a Building Warrant of Fitness?

Not every property requires a BWoF. It only applies to buildings that include specified systems listed on the compliance schedule. These are systems designed to protect occupants in case of an emergency, such as:

  • Fire alarms and smoke detection systems
  • Emergency lighting and exit signage
  • Lifts, escalators, and automatic doors
  • Sprinkler systems and ventilation systems


In general, commercial, public, and multi-unit residential buildings require a warrant, while most standalone homes do not. However, if a house includes complex systems, for example, a lift or automatic fire suppression system, it may also fall under these requirements.

What’s Involved in Getting a Building Warrant of Fitness

Getting a Building Warrant of Fitness (BWoF) in New Zealand involves a few key steps to make sure your property stays safe, functional, and fully compliant with the Building Act 2004 and local council requirements.

1. Review the Compliance Schedule

Start by reviewing your compliance schedule. This document lists all the specified systems in the building, such as fire alarms and emergency lighting, that must be regularly inspected and maintained. It’s provided by your local council when the building receives its consent.

2. Engage Independent Qualified Persons (IQPs)

Only Independent Qualified Persons (IQPs) can perform inspections and maintenance for a BWoF. They ensure that each listed system meets the required performance standards and safety rules.

3. Complete Inspections and Maintenance

Throughout the year, each system must be tested and serviced according to the procedures on the compliance schedule. Any faults should be repaired quickly to keep the building safe and compliant.

4. Collect Form 12A Certificates

After inspection, each IQP issues a Form 12A certificate, confirming the system has been checked and maintained over the previous 12 months. These certificates are essential supporting documents for your BWoF application.

5. Prepare and Sign the Annual Form 12 (BWoF)

Once all systems have been verified, the building owner must complete and sign the Form 12 - Building Warrant of Fitness, confirming that:

  • All systems have been inspected by IQPs.
  • Maintenance and reporting records are current.
  • The building has fully complied with the Building Act 2004.


6. Submit to the Local Council and Display the BWoF Certificate

Finally, submit your Form 12 and all Form 12A certificates to the territorial authority (local council). A copy of the BWoF certificate must be displayed publicly inside the building to show it meets legal and safety standards.

Common Mistakes That Delay BWoF Approval

Even small errors in the process can lead to delays or non-compliance notices. Some of the most common mistakes include:

  • Missing or incomplete Form 12A certificates from IQPs.
  • Failing to carry out regular maintenance or repairs.
  • Not updating the compliance schedule when systems change.
  • Forgetting to display the current BWoF certificate in the building.
  • Not submitting the documentation to the local council on time.


Avoiding these mistakes helps you maintain a seamless annual renewal process and ensures your building warrants stay valid.

Electrical systems are a crucial part of keeping your building safe and compliant. Systems such as emergency lights, alarms, and power controls often fall under the building’s specified systems and must meet strict performance standards to qualify for a certificate of compliance.
