Unworkable and inconsistent regulations are making agricultural spraying near-impossible in some areas, says the New Zealand Agricultural Aviation Association (NZAAA).
A number of regional and district councils around the country are reviewing their long-term plans and proposing some changes which affect those who use planes and helicopters to spread fertiliser.
The NZAAA has been raising concerns over some of the proposed changes in different regions across the motu.
Chairman Bruce Peterson said some helicopter and fixed-wing aircraft pilots fly up to 100 times a day but some councils have proposed limiting them to only two flights a day.
One council proposed no commercial flights without a resource consent.
“Industry is being challenged with councils’ and district plans that all have to be reviewed,” Peterson said.
“Most of them [the controls] are around noise and drift and hours of work, etc. so they’re all different.
“It’s very difficult when an operator might go across three or four different plans and different rules and you can do one thing in one and one in the next.”
He said the association had disputed a number of regional or district plans restricting the use of agricultural aviation services – and had more on the list for mediation.
