About Us

Master Build Services Limited is a wholly owned subsidiary of the Registered Master Builders Association of New Zealand Incorporated and provides the Master Build Guarantees. We are the oldest and largest provider of guarantees in New Zealand and were the first to offer these products to our members’ clients. Nearly 100,000 homes have been covered by our guarantees over the last 20 plus years and our products continue to evolve to satisfy consumer needs. We have the largest and the most competitive range of guarantee products in the market.

Master Build Services has its own Board of Directors and has the additional backing of the Registered Master Builders Association of New Zealand Inc which is over 110 years old.  The company undertakes an actuarial review by an independent actuary from Australia every six months and is independently audited by Deloitte annually.

Master Build Services Limited was established in 1987. The guarantee came into force in 1991 when new home guarantees were offered on an optional basis. Additions & alteration guarantees were provided from 1992, also on an optional basis.

In 1995 the new home guarantees became compulsory for all Registered Master Builders on every qualifying dwelling built under a full building contract. In 1998 it became compulsory for all Registered Master Builders to offer a guarantee on all qualifying residential building work, whether a new home, or additions and alterations work, and whether built under a full contract or a labour-only contract.

Master Build Services has developed and adapted its products over the years to increase protection for our customers and meet the ever changing market. We currently offer a suite of 10 year guarantees tailored to the individual needs of anyone who has engaged a Registered Master Builder. 

We have a proud history and a brand that is widely recognized as a hallmark of quality. The benefits of having a guarantee are invaluable.

Build with confidence: Engage a Registered Master Builder and insist on a Master Build Guarantee.
