Combined Building Supplies

Combined Building Supplies (CBS) is a buying group serving independent builders and tradespeople in New Zealand and Australia. By combining members’ purchasing power, CBS helps smaller businesses access pricing and supplier relationships typically associated with larger building groups. Members can receive discounts of 5–50% across a collective of more than 30 suppliers, covering building materials, appliances and other trade-related products, with specific offers varying by supplier. Membership also includes an annual rebate based on yearly spend and opportunities to connect with peers through free member meet-ups.

CBS supports members through its registration and setup process, providing a welcome pack and help establishing supplier accounts so they can access available savings. The organisation also shares practical resources, industry updates and guidance through its blog, Construction Pulse, advocacy work and submissions on building-sector issues. Additional member offers include services such as job-management software, electricity, solar, tools, plumbing and bathroom products, and car rental, subject to each provider’s terms.
