New Zealand has always been a leader in the aerial application of agricultural chemicals. Much of this is due to the hilly and inaccessible nature of some of New Zealand's productive land. Early on the Tiger Moth was used by replacing the forward cockpit with a hopper. These days the Tiger Moth has been replaced by more modern aircraft such as the Kiwi designed and built PAC Cresco, helicopters and the Air Tractor.
A more unusual conversion is the spray-boom equipped Tiger. This is perhaps the last in the world and as in previous years, put on a great display. Aircraft in the airshow display where DH82A Tiger Moth ZK-ANL, followed by Schweizer 269C, ZK-HEU and Air Tractor AT-402B, ZK-PCC.
