The Government says the almost $30 million it has paid out to consultants doing initial work on the IRD's massive IT upgrade or "business transformation" is money well spent.
In response to questions from Labour's revenue spokesman, David Cunliffe, Revenue Minister Todd McClay yesterday confirmed more than $29 million had been spent on the project's consultants since 2009.
According to information supplied to Mr Cunliffe by Mr McClay's office, that included $23 million paid to French IT consultant Capgemini.
Ex-Revenue Minister Peter Dunne two months ago confirmed the Government was proceeding with the project, which was expected to cost as much as $1.5 billion over 10 years.
Mr McClay yesterday said he was not aware whether Capgemini had provided an estimate of the total cost.
