The Emissions Trading Scheme (ETS) has again been criticised at the Federated Farmers conference in Rotorua.
The federation remains opposed to the Government's plan to include agricultural emissions in the scheme by 2015.
Deputy Prime Minister Bill English and leaders of the Labour, Green and ACT parties who met with delegates on Thursday were left in no doubt about farmer opposition.
ACT leader Don Brash was applauded for stating his party would push to have the scheme abandoned.
But Labour leader Phil Goff reiterated his party's intention to move agriculture into the ETS in 2013 if it becomes the government after November's election.
