The Auditor-General is considering bringing forward a review of government procurement after financial irregularities at Fuji Xerox, which has an all-of-government contract.
However, he will wait for a Ministry of Business, Innovation and Employment investigation into the contracts before deciding whether he needs to act on the issue.
Japanese parent Fujifilm Holdings last month released a report by an independent investigation committee which revealed "inappropriate accounting" in operations in New Zealand and Australia amounting to roughly $355 million between 2011 and 2016.
Fuji Xerox's chairman Tadahito Yamamoto, deputy president Haruhiko Yoshida and two Fuji Xerox directors, Katsuhiko Yanagawa and Jun Takagi, have all resigned.
The New Zealand business has said it takes the findings "very seriously and is committed to resolving past issues and ensuring that there is no recurrence."
