New Zealand Auditor-General John Ryan has formally rejected an application by Orion Health CEO Ian McCrae to audit the Ministry of Health’s procurement of the COVID immunisation register (CIR) and the national immunisation solution, as well as the national screening solution (NSS).

Mr McCrae requested an audit in May, saying the ministry had ignored normal procurement processes and had used incorrect information in its business case. He also criticised the $38 million price tag for the overall infrastructure.
