A performance review of the Treasury reveals declining ministerial confidence following significant errors in economic forecasting and cost oversight.

Ministerial confidence declines

The Treasury Performance Improvement Review, the first assessment of its kind in a decade, indicates that government ministers are losing trust in the advice provided by the agency. This decline in confidence follows several high-profile errors in fiscal guidance and economic projections.

The report highlights a growing gap between the Treasury's outputs and the requirements of decision-makers within the government. Ministers have increasingly expressed concerns regarding the reliability of the department's data and its ability to anticipate shifts in the fiscal landscape.

Critical forecasting and oversight failures

A central finding of the review involves the inadequacy of current economic forecasting models. The report labels the department's recent economic predictions as 'weak,' noting that these inaccuracies have hindered effective long-term planning.

Beyond macroeconomic trends, the review identifies specific instances where the Treasury failed to flag significant budget escalations. These oversights include:

• Missed cost blowouts associated with the ACC.
• Unanticipated expenditure increases within Health NZ.

The inability to identify these rising costs early has prevented ministers from implementing timely budgetary interventions, leading to unexpected pressure on public finances.

Structural implications for the Treasury

As one of the four most critical components of the New Zealand government, the Treasury's performance directly impacts national economic stability. The review suggests that the current framework for economic modelling and departmental oversight requires significant reform to restore its credibility.

The findings suggest that the Treasury must improve its ability to integrate emerging fiscal risks into its core advice. Addressing the 'weak' forecasting and the lack of visibility regarding agency-specific cost increases remains a priority for the department's leadership to regain the trust of the executive branch.
