In another separate incident in June 2010 two airliners were found to have had a high potential to have breached the 1000 foot vertical separation required, according to a report by the New Zealand Transport Accident Investigation Commission. Both were Boeing 737 aircraft, one operated by Qantas Airways and the other by Pacific Blue. The report states that whether the minima was breached was not investigated further because in the circumstances it was clear that the potential for such a breach was high and that alone was a safety issue that needed addressing.
