Helicopter operators seeking long-term consents to continue aerial drops of 1080 poison in the Waikato region have been restricted to just a year.
But a Coromandel conservation group campaigning against 1080 use for possum and other pest control says the restrictions still do not go far enough.
Two companies had asked the Waikato Regional Council to renew their aerial application consents for 10 and 20 years.
But after concerns raised by the Upper Coromandel Landcare Association, the companies changed their applications to one-year consents that will have to be renewed when that period expires.
The conservation group has welcomed that but says the public should also be able to have a say before final approval is given for the poisoning operations.
The regional council says because the consents are short-term, they will not need to be publicly notified.
