New Zealanders have splashed headfirst into a national debate over environmental regulation after a dolphin sighting cancelled a day of the visiting SailGP regatta.
New Zealand's leg of the international sailing competition was cancelled on Saturday when a Hector's dolphin was spotted near the start line in Lyttelton Harbour, near Christchurch.
The Hector's dolphin is the smallest and rarest marine dolphin in the world, according to the WWF, with just 15,000 animals, all located near New Zealand's coast.
