The Certified Builders Association of New Zealand Inc is a community of craftsmen and was established in 1998 to recognise and promote qualified builders. Unless the builder is trade qualified they cannot become a member of the Certified Builders Association.

One of the main objectives of the Certified Builders Association of New Zealand Inc is:

“To provide New Zealand consumers with the assurance that our members are trade qualified builders who adhere to strict guidelines for standards of workmanship and business practice.”

Certified Builders Aims & Goals

The formation of the Certified Builders Association of New Zealand Inc provides benefits for the builder and the consumer.

The fundamental aim of the Association is to promote the skill of its members, establishing a clearly identifiable level of

• competence,

• consistency and

• excellence

for the building public and the profession. The consumer benefits from the knowledge that our members are trade qualified.

Those who are trade qualified will consistently perform to a greater degree of competence than those who are not trade qualified.

Who can join the Certified Builders Association

Membership of our Association is open to any builder who meets our membership criteria. The first requirement is to hold a recognised trade qualification equivalent to or better than National Trade Certificate in Carpentry Level 4. But trade qualifications are not the only criterion, and to ensure that our high standards are maintained CBANZ takes a number of factors into account. As a voluntary membership organisation CBANZ has total discretion over who it admits to membership, and why. Although it is not obliged to give any reasons for its decisions, CBANZ looks for such things as a reasonable history of stability and success, continued solvency, absence of complaints by customers & suppliers, a good untarnished reputation and brand, and consistently high standards.
