Just checking this forum since my grandfather’s photos are included and I’m really quite obsessed with learning about anything I can about his time spent as a flight lieutenant for the RNZAF (Mortimer Tuke Vanderpump).

Welcome to the hanger!
I believe the photos are from the RNZAF Museum's online picture library, if you haven't seen it yet here's a link to the results when I searched using your grandfather's last name:

Also, a place you may be able to learn more about his service is the WONZ forum:
