Southern QA is a privately owned Christchurch headquartered business, with branches in Auckland, Hamilton, and Invercargill. The company was founded in 1987 taking the opportunity to establish in the South Island where Inspection and Quality Assurance services were scattered, and limited in their resources.

Southern QA’s model is, as business allows, to invest in human and technical resources to provide the very best Inspection and Quality Assurance services available.


SQA has a new branch open in Wellington as of April 1 2018. It will be under the stewardship of Albert Caldwell, who will be familiar to many in the engineering, construction, and quality assurance industries. Albert can be reached on 0274434513.
