Today’s on-this-day photo shows Britten-Norman BN-2A-III Trislander, ZK-LGF, of Great Barrier Airlines.

It’s looking a little forlorn sitting at North Shore Aerodrome in 2014.

Also… what’s with “BN-2A-III” and not, like, BN-2C, or even BN-3? (There were BN-2B and BN-2T models, both with just the two engines.)
