About us
-
Signal Audits is a CA ANZ-qualified audit firm based in Auckland, providing audit and assurance services to small and medium-sized enterprises (SMEs) and public benefit entities (PBEs) across New Zealand.
We help organisations meet their statutory obligations, strengthen governance and approach their financial reporting with clarity and confidence - without unnecessary technical jargon or complexity.
-
Many SMEs, PBEs and other smaller charities need high-quality audit and assurance services, but don’t always feel valued by larger firms.
As some firms shift their focus toward higher-margin advisory work, smaller organisations are often left feeling underserviced or priced out.
Signal Audits was founded to bridge that gap.
We deliver:
The same professional standards
The same leading audit software
The same regulatory compliance
All with a more personal and responsive service model.
Our focus is straightforward: to provide reliable, independent assurance at a fair and transparent cost.
-
We primarily support:
Small and medium-sized enterprises (SMEs)
Registered charities and public benefit entities (PBEs)
Churches, schools, early childhood centres, sports clubs, and community organisations
Bodies corporate and any other organisations requiring agreed-upon procedures
Whether you require a statutory audit, independent review or an agreed-upon procedures engagement, we will adapt our approach to the size, complexity, and regulatory requirements of your organisation.
-
Based in Auckland, Signal Audits works with organisations throughout New Zealand. We’re proud to support clients from major centres to smaller regional communities, bringing the same professional standards and personal attention no matter where you’re located.
