Does anyone recognise these Battle of Britain pilots

I was just doing some hunting around the internet to find out whe the film premiered in NZ, but have not been able to find a date. Does anyone know?

I did find a Canadian newspaper article that stated in the Uk for the first premiere (15th of September 1969) around 150 fighters ‘aces’ as it put it gathered to remember their time in the real battle. I wonder if anyone has a list of which veterans were there? I guess some UK-based kiwis may have attended, like Al Deere, Bill Wells, Keith Lawrence, Bernie Brown, etc?

It was neat to find the photo i linked above and see that Sir Keith Park attended. My friend I borrowed it off was there with her Dad, Bill Kain, and she said Sir Keith made a speech to the audience and then got all the battle veterans to stand up and be introduced.
