Police officers should have followed procedures when abandoning a high speed chase which ended in the death of a 22-year-old man, the Independent Police Conduct Authority (IPCA) has found.
Troy Peter MacKay was killed in Christchurch on June 20, 2010 when his Subaru Impreza hit a tree as he was being pursued by police.
The investigation concluded the officers were justified in starting the pursuit and largely complied with policy throughout, but should have come to a complete stop and turned off their lights and siren when abandoning the chase.
The officers began to chase Mr MacKay after seeing his car being driven in a dangerous manner along Blenheim Rd in the city.
The car was seen weaving in and out of traffic before it turned on to the Christchurch South Motorway and then into Halswell Road, where it lost control and struck a tree at a speed of 150km/h.
