Online accounting software provider Xero is concerned new protocols being drawn up by Inland Revenue could allow government departments to go on "fishing expeditions" through taxpayers' business records.
The tax department is developing guidelines with cloud computing providers to ensure it can gain access to New Zealand companies' information stored in overseas data centres.
"The IRD are trying to get their head around the cloud and tax evasion at the moment," said Julian Smith, general manager of MYOB, another local accounting software firm.
New Zealand businesses using cloud-based accounting systems will often have their business records stored overseas. Xero users, for example, have their information stored in United States-based data centres.
Rod Drury, Xero's chief executive, said the Wellington-based firm supported the guidelines and had worked with the IRD on developing them, but was also working with the Privacy Commissioner to try to ensure the right balance was reached and government departments did not abuse powers when accessing data.
