Grant Thornton’s audit services go beyond signing off historical information and our approach is not typical of firms that only look in the rear-view mirror to see what happened last year. We look in more depth at the commercial issues that flow from the audit and the business risks that are of real importance to you. We provide value-added audit reports with robust independent opinions and actionable insights that help businesses succeed and grow.

To produce outstanding audit work for leading New Zealand organisations in both the public and private sectors, we use one audit methodology globally, which means we can offer you consistent, high quality services wherever you are in the world. During our audits, clients enjoy access to partners and staff, all delivering a uniquely approachable level of service.

Our team of experts have extensive experience in all aspects of audit and assurance:

  • External audits focused on financial statements
  • Internal audits
  • One-off reviews of systems and controls
  • Agreed-upon procedure reports
  • Other regulatory and compliance audits
