The Coroner has found the death of a tourist driver may have been caused by a combination of unclear signage and unfamiliarity with New Zealand road markings.
26-year-old Kim Taewook was killed in November 2013, when the rental car he was driving on State Highway 80 did not give way at the intersection with State Highway 8 and drove directly into a path of a truck.
Mr Taewook was a student visiting from the Republic of Korea. He was driving from Christchurch to Aoraki Mt Cook with an unrelated passenger when the crash occurred.
Blood taken at autopsy found a trace of alcohol, which was thought to have been non-contributory to the crash.
A police investigation noted some deficiencies in the signage at the intersection. Constable JB Mcintyre of the Canterbury District Serious Crash Unit found the warning sign 200 metres prior to the intersection could easily be missed by a driver travelling 100km per hour.
