On 18 December 2020 the Minister of Local Government confirmed that a Commission would be appointed to Tauranga City Council, stating: “The Council’s response has not presented me with sufficient evidence on how it is addressing its problems.

The external review the council commissioned into the 22 January 2026 landslide at the Mount Maunganui Beachside Holiday Park, released on 19 August 2026, states that “TCC knew of the landslide risk to the campground” and that “This was a systemic failure with tragic consequences.” It places the criticism with “the organisation that left the campground manager and his staff so ill-equipped and unprepared”, says “The failure was not the fault of any one person”, and makes no finding as to civil, criminal or disciplinary liability. The council accepted the findings and recommendations the day the report was released.

The Office of the Auditor-General’s letter of 26 May 2021 on the council’s Harington Street car park building project, written in place of a full inquiry, said that “several aspects of the Project … did not accord with good procurement or governance practice”. It cited an external review for the council that identified “gaps in documentation and information” and “conflict of interest management practices not aligning with good practice”.

On 26 August 2025 the Office of the Auditor-General wrote that it did not intend to carry out further inquiry work on six council property and spending decisions. On the Marine Precinct sale it said it had earlier declined because of High Court proceedings, that those had concluded, and that an inquiry was unlikely to add value. On the other five matters it stated: “We have not seen evidence to substantiate the concerns raised with us about the probity of the decision-making processes”. It said it was not its role to judge the merits or price of the decisions or compliance with the Local Government Official Information and Meetings Act 1987, and noted that “it was sometimes difficult for us to establish the process the Council had followed, based on publicly available information”.
