Welcome to the Office of Transport Safety Investigations

The Office of Transport Safety Investigations (OTSI) is an independent statutory body. Its head, the Chief Investigator, reports directly to the Minister for Transport.

OTSI was established as an independent body to investigate safety occurrences involving bus, ferry and rail transportation. The purpose of these investigations is to identify why an occurrence took place and make recommendations to prevent recurrence. To support this style of investigation, a 'just culture' approach is used.

News

From July 2009 OTSI will be supporting the introduction of the new national Contributory Factors Framework (CFF) which will assist in analysing factors that emerge from rail investigations. More information.
