The New Zealand Transport Accident Investigation Commission determines the circumstances and causes of selected aviation, marine, and rail accidents and incidents with a view to avoiding similar occurrences in the future. It does not ascribe blame. TAIC helps New Zealand fulfill international obligations to conduct independent and impartial safety-focused investigations, as required by United Nations conventions. The Commission pursues its goal of 'No repeat accidents - ever!' through its investigations and findings, and, where appropriate, making recommendations to people and organisations that are able to change rules or practices to improve transport safety. TAIC's five corporate strategic objectives are to: 1. Deliver sound, cost effective Crown entity performance 2. Develop and maintain responsive reciprocal stakeholder relationships 3. Share inquiry and entity information 4. Develop and maintain capable staff 5. Properly conduct investigations
