Et Exsultavit by Bach was sung by Bianca Andrew with Handel's The Trumpet Shall Sound sung by Ian Campbell.
In his eulogy, Air New Zealand chief pilot Captain David Morgan said Bryan Wyness was a remarkable man.
"He was a fine man who has left a fine legacy to aviation in New Zealand and the world."
Mr Wyness had led Air New Zealand through many operational changes especially in the field of safety, he said.
"His operational structure and rules have been adopted as gold standards especially his study about the fatigue system, throughout the world."
He was an avid follower of Richards Wagner's The Ring Cycle and his favourite piece Entry of The Gods into Valhalla was played in Bryan Wyness's honour by organist Nicholas Grigsby at the close of the service.
