The Chambers of Commerce are voluntary, membership-based organisations. Membership is open to all types of businesses, and this is a particularly effective way to establish new business contacts and find out about local business conditions. Chamber services include:
- advocacy
- business education
- international trade services
- issuing Carnets and Certificates of Origin
- business advice/mentoring
- social functions for meeting/networking with new members and developing business
The Chamber network includes 31 Chambers representing about 20,000 businesses. About 75% of the members in New Zealand are small- and medium-sized businesses and more than one-third are involved in international trade.
