The total cost of Immigration New Zealand's failed biometrics technology upgrade has blown out to almost $40 million, after at least another $6 million in wasted expenditure was identified this week. RNZ

Immigration Minister Erica Stanford released a fresh statement on Wednesday disclosing the additional costs. The revelations emerged after Stanford's staff discovered an error in information previously provided to her by the Ministry of Business, Innovation and Employment (MBIE).

MBIE chief executive Nic Blakeley subsequently advised Stanford that a further $6 million in associated project costs had been identified. Blakeley said he could not be confident the additional $6 million represented the full extent of the expenditure, and made the decision to commission an independent financial auditor to establish the full scale of the spending.

Stanford had previously told reporters that more than $30 million and seven years of work had been wasted on the biometrics upgrade, with nothing to show for it. The project was intended to overhaul Immigration NZ's biometric capability.

The latest disclosure adds to what was already a serious political problem for the ministry. In June, an independent report found that immigration officials had deliberately withheld information about the failed technology upgrade. The same report found officials had used what it termed 'creative accounting' to avoid scrutiny over the expenditure. Scoop

Those findings prompted a parliamentary debate on 23 June 2026, formally titled 'Immigration New Zealand—Withholding of Information'. The matter falls within the portfolio oversight of the Education and Workforce Committee, which is responsible for immigration matters in the House. Hansard

At the end of June, Stanford said her confidence in the ministry had been 'knocked' by the failed upgrade. Her language has sharpened since then. Stanford told reporters her trust in information provided by officials had been severely damaged and was getting worse. She said the latest revelations raised significant questions about MBIE's financial controls.

Stanford has now referred the matter to the Public Service Commissioner, as well as to the Michael Heron inquiry currently underway into the broader bungled upgrade. She said the Public Service Commissioner would consider whether the Heron inquiry's scope needed to be widened in light of the newly identified expenditure.

Stanford declined to say whether she had confidence in Blakeley as MBIE's chief executive.

NZ First leader Winston Peters called the latest revelation a 'shocker' and said heads should roll.

The broader context here is one of a minister increasingly at odds with her own officials over the reliability of basic financial reporting. Stanford's decision to refer the matter simultaneously to the Public Service Commissioner and the Heron inquiry signals that the government's appetite for relying on internal MBIE assurance has effectively run out. The decision to bring in an independent financial auditor at the chief executive's own initiative also suggests MBIE itself cannot confidently account for what has been spent across the life of the project.

For those working in the political and public service ecosystem, the stakes are now pointedly institutional. A minister publicly stating that her trust in officials is 'severely damaged' and 'getting worse', combined with a refusal to express confidence in a chief executive, is about as direct a signal as the Westminster convention allows. Whether the Public Service Commissioner widens the Heron inquiry's scope, and what the independent financial audit ultimately establishes about the full cost, will determine whether this remains a contained fiscal embarrassment or escalates into a broader public service accountability matter.
