In July 2011 newly installed runway lights were turned on for the first time. The lighting upgrade was designed to lower diversion rates at the airport due to low visibility. Queenstown is the last major airport in New Zealand to receive such an upgrade. The $2 million project included 34 transformers, 25 km of airfield lighting cable, 124 lights, and was funded by Airways NZ. Until this upgrade, the airport had only Precision Approach Path Indicators (PAPI) available for pilot aid, so flying was limited to daylight hours.
