A tractor protest at the weekend showed farmers feel threatened about their future, says a Northland mayor.
The protest took place in the township of Ruawai, at the northern end of Kaipara Harbour.
Between 120 and 150 farmers turned up, most of them by tractor.
They said a suite of measures, zero carbon legislation, the latest water plan and the Billion Trees Programme could force some of them off their land.
