In April the Herald talked to one of the protesters who scaled Parliament this morning after he boarded an oil rig in the middle of the Pacific Ocean.
Jonno Smith, 32, from Auckland, had scaled the 38,000 tonne Arctic-bound oil rig around 7am Honolulu time with five other Greenpeace climbers.

In a telephone interview with the Herald from the Polar Pioneer - located 720 miles north-west of Hawaii - Mr Smith said he had been climbing for 13 years, and revealed he travelled around New Zealand working as a contract climber.
He started volunteering with Greenpeace two years ago but said this was his first time climbing aboard a ship.
