"The pilot came on shortly after and said that we had been hit by lightning, they had checked all the systems and everything was okay,'' she said.
Despite the shock she wasn't worried by it because she has "huge confidence in pilots''.
"I'm glad I've done it now, it's off the bucket list, not that I particularly wanted to do it,'' she said.
A spokeswoman for Air NZ confirmed the strike, saying: "Air New Zealand flight 504 from Christchurch to Auckland was hit by lightning on approach to Auckland this morning. There were 163 passengers on board.
"The aircraft will now be inspected by engineers before being cleared to return to service.
"Lightning strikes are not uncommon in the aviation industry and aircraft are designed with this in mind.''
