there are a few B4's here in NZ, but very few people sling with them. mostly they are used on private ops, charter or tourist ops. the guys i can think of that run them are advanced flight in Auckland, pretty much all private and charter work, over the top in QT on tourist work, i think North Shore Heli in Auckland might have access to a few, and lowe walker in Napier.
the last one did some ag work with theirs
, only spreading urea, not spraying... its part owned by a farmer, so thought they may as well give their pilot something else to do, and he had the experience so why not. Pretty sure the only B4 in NZ with a hook, vaguely remember he said it was good for a ton without too much trouble. thats with all the VIP interior still in it, air con on, about an hour gas, go to work...
