Jeanette Fitzsimons, centre, is welcomed home after almost three weeks at sea by Catherine Delahunty and husband Harry Parkes. Four of the six yachts, which made up Oil Free Seas Flotilla, arrive in Auckland. They were protesting against oil giant Anadarko drilling at a site over 100 nautical miles off the west coast of New Zealand, and in waters around a kilometre and a half deep.They were at sea for close to three weeks. The Greenpeace sponsored yacht SV Vega spent seven days inside the 500 metre exclusion zone as the Noble Bob Douglas prepared to start drilling. The yachts arriving in Auckland are SV Baltazar, SV Friendship, SV Shearwater II and SV Vega. SV Ratbag arrived back at her home port in the Bay of Islands while SV Tiama is heading south. The flotilla is a coalition of individuals and boat owners who oppose deep-sea drilling and the new legislation that takes away New Zealanders long-standing right to peacefully protest at sea.
