As anger mounts on the West Coast over the suspension of 230 Spring Creek coalminers, protesters are planning to picket the Solid Energy head office in Christchurch.
About 1000 people marched through Greymouth on Tuesday to protest against the suspension of the mine, which injects $37 million a year into the Greymouth economy.
Grey District Mayor Tony Kokshoorn said yesterday that the Engineering, Printing and Manufacturing Union was looking to take a busload of miners to picket the corporate office.
Mr Kokshoorn said he would lead the charge should the protest reach Canterbury.
He said opposition to the mooted mothballing of Spring Creek was mounting.
