After seeing the Hairy Mole Rat's Wairarapa Balloon Festival photos I had a look at their Facebook page where there were photos of a few of the other balloons that there were there:
ZK-PJK is a Boland Snakeskin 70-12 from Carterton.
ZK-PNG is a Ultramagic C-77 from Cambridge
ZK-LOP is a Boland 52-12 from Hamilton and ZK-FBA3is a Kavanagh C77 from Wellington.
