The Transport Accident Commission (TAIC) of New Zealand is undertaking a formal investigation into this accident. As part of that work, TAIC requested the assistance of human factors specialists at the Australian Transport Safety Bureau (ATSB), to assess the likelihood and extent of any performance impairment to the master and second mate due to fatigue. To protect the information supplied by TAIC, the ATSB initiated an investigation under the provisions of the Transport Safety Investigation Act (2003).
Following the analysis of the sleep and work data supplied by the TAIC, the ATSB conducted analysis of the fatigue likelihood and produced a report which was provided to TAIC on 26 August 2014.
