The Office of the Auditor-General has stepped into deep political water with its decision to investigate the Government's handling of bids for an international convention centre in Auckland.
It is calling into question the conduct of a Prime Minister whose standing remains very high in the country despite some unpopular steps this year. It cannot be easy, even for an office with statutory independence, to ignore the political climate and take a step such as this. The office can be congratulated without that comment prejudging the issues in any way.
Opinion has been sharply divided on the propriety of John Key's personal intervention which appears to have led directly to an offer from SkyCity casino and the decision last year to accept it over several other proposals. Many see it as a very good deal, the only one that would not require a direct subsidy, and see nothing wrong with Mr Key's role in it. Others find the deal disturbing mainly because the casino wants additional gambling facilities in return, but not only that.
Tenders for public projects ought to be kept at arm's length from those with the ultimate power of decision. The procedure must be fair and transparent and no bid should appear to have the inside running. That is essentially the focus of the Audit Office inquiry announced yesterday.
The Deputy Auditor-General will examine the overall process for seeking and assessing proposals, the adequacy of the assessment of likely costs and benefits of each, and any other matters it finds it desirable to report on. The second term of reference could allow the office to pass judgment on the implications of the bid for problem gambling but a ruling on the possible public costs seems unlikely until government officials negotiate the finer details of the deal with SkyCity.
