KEY POINTS:
A policewoman is in line to receive a commendation after hurling herself at a Greenpeace boat to quell a protest that caused chaos at a busy port.
Constable Sarah McLauchlan was one of about 30 police called to the protest on Tuesday in which Greenpeace protesters used their Rainbow Warrior II vessel to block a coal export ship's departure, and attached themselves to the ship's hull.
Six people were arrested and charged during the drama at Lyttelton Port, near Christchurch.
The Herald understands further charges will be considered at a meeting of police and maritime authorities today, including possible action against the Rainbow Warrior II skipper and Greenpeace itself.
Police have criticised Greenpeace for using tactics which drew such a large amount of police resources, but Greenpeace says the police numbers were "totally unnecessary".
Ms McLauchlan was captured on camera diving from a craft carrying police to an inflatable Greenpeace boat to prevent it blocking the coal ship's departure. She could not be reached yesterday while out on the beat.
But Inspector Malcolm Johnston said Ms McLauchlan had been recommended for the District Commander's Commendation by her sergeant, who rated highly her actions in the circumstances.
She put herself at risk by leaping across the water in 15 to 20 knot winds and choppy seas, Mr Johnston said.
"At the end of the day there was an element of danger. She could have hit her head and fallen into the water unconscious." The craft she jumped on to was an "integral part" of the protest blockade and had to be stopped, Mr Johnston said.
Simon Boxer of Greenpeace claimed Ms McLauchlan only had to ask to go aboard the inflatable craft.
The Rainbow Warrior is due to arrive at the Port of Otago today in the next step on a national climate change tour. A spokeswoman for Lyttelton Port would not comment when asked if the Rainbow Warrior would be allowed back.
