Northland Conservation Board chairman Mita Harris said conviction was the "last resort" and encouraged hapu and iwi to place rahui on forests to prevent the crime from happening.
"I mean, it's my position law and enforcement is the last resort. It's lore versus law. Put rahui in place, let's get it known the numbers aren't as great as they once were. I mean people used to go in the forest and bring back four birds - you just don't do that any more," he said.
"Hapu need to take it upon themselves look at what they've got in there rohe " whether it be kukupa or kiwi and decide on these things. It's tino rangatiratanga, self-determination."
The DOC spokeswoman said they relied on reports of illegal hunting, and also monitored areas where hunting was known to take place.
Forest areas where poaching had occurred included Reatea, Omahuta, Puketi, Russell, Waipoua, Tutumoe, Herekino and Utukura. She said, in the past three years, DOC compliance rangers responded with police on at least two occasions where information was received from the public. One was in 2013, in the Kaikohe region, and the other in 2014, in the Kaitaia area.
"On both these occasions, which involved travel to remote locations, the alleged offenders had already moved on.
"People should report any incidents of illegal wildlife hunting to the DOC emergency hotline 0800 DOC HOT (0800 362 468). Any specific information in relation to the location of the alleged offending or identity of the offenders is useful."
Ngapuhi runanga chairman Sonny Tau will appear in Invercargill District Court next month facing charges of hunting/killing kukupa and possessing the protected birds, after he was allegedly found with kukupa at Invercargill Airport on June 16.
The last two men convicted for kukupa offences were jailed in 2008 for six weeks. Michael Stanley Sampson, then 36, and Murray William Ogle, then 33, of Horeke, each pleaded guilty in the Kaikohe District Court on February 21 that year to hunting, killing and possessing kukupa in the Omahuta Conservation Forest on May 24, 2007.
