The dredge at work in the Blaketown lagoon yesterday. Photo: Greymouth StarTwo years after the Greymouth port purchased a second-hand dredge from Tasmania, it is finally working. The Greymouth Star was given a demonstration yesterday and witnessed how a mechanical cutter head is lowered 3-4m to the silted bottom of the Blaketown lagoon. However, port staff said yesterday the dredge did not in fact need Maritime NZ certification. Including alterations since it arrived in Greymouth, the dredge probably owed the council about $300,000, he said.
