"Just tell them to go away" - that was the loudest message at a community meeting at Whakapara about how to stop an Australian gold mining company going on to private land to carry out ground tests.
About 60 people also heard at Tuesday night's meeting organised by MineWatch Northland that landowners should avoid chatting with Evolution Mining representatives "around the kitchen table".
Speakers said locals "engaging" at any level gave the company a foot in the door and would weaken a united anti-mining community stance.
"Never sign anything without advice. The community needs to stand united because mining companies can carry out their activities under your land from your neighbour's side of the fence," MineWatch member Tim Howard said.
Landowners also need to be aware any access agreement is binding on the property, even if it is later sold or inherited, he said.
