Government auditors have asked an agency which criticised aviation regulators for poor record-keeping to improve its own reporting performance.
Auditor-General Lyn Provost says the Transport Accident Investigation Commission, although scoring well on other measures, needs to provide better information about the services it provides.
A report to Parliament from her office about the performance of various transport organisations came as the commission was criticising the Civil Aviation Authority for a lack of data and research about whether the safety of flight training had declined amid an increase in fatal crashes in recent years.
The report gave the accident commission top scores for two categories covering management controls and financial reporting, but it was the only one of seven organisations to receive a "needs improvement" reprimand for information about its service performance.
Commission spokesman Peter Northcote said the report was not suggesting there were any organisational failures, but the Auditor-General's office wanted to see a closer linkage being made "between what we do and safety improvements in the [aviation] sector".
