Farmers say the 2019 Budget has left a critical gap in the Government's commitment to conservation.
Federated Farmers said in a statement there was no additional funding for the QEII National Trust or the Ngā Whenua Rāhui Fund.
Arable and biosecurity spokeswoman Karen Williams said there was also "woefully inadequate" funding for the control of wilding conifers.
She said the "extremely modest" increase in funding for the National Wilding Conifer Control Programme meant its work would be going backwards in terms of managing the pest.
"We hoped to see the wilding conifer programme receive more like $25 million per year.
