I presume you flew in ZK-PBY?
I saw her in New Plymouth in November, looking a bit sorry for herself:
There are some corrosion issues in the wing, minor from a structural point of view, but major from the point of view of the labour involved. It's a big wing!
I was able to sit in the cockpit during an anti-det run. An interesting experience and a wonderful noise, but I'm glad I wasn't asked to clean up afterwards:
