I actually stumbled upon this collection on social media, on a page called Pukekohe Motor Raceway. I contacted the page manager and asked for permission to post their pics here, and have just been given the green light.
I'm actually still trying to gather info on who took all these photos. Is it one person, or several people? All will eventually be revealed I'm expecting.
But in the meantime, I wanted to start posting these up, because there are some really great shots in here. They appear to be mostly amateur shots, but some are taken at the start/finish line in the pits, so I wonder if whoever took them had permission to stand where they were standing in order to get them. Some were snapped on the track itself, just prior to race start.
There are around 75 photos in all, and they span from the late 1960s right through to a historic event(s) in the mid/late 1980s.
Here you go, enjoy. And feel free to fill in any gaps.
