Hundreds of marchers rallied in Kumeu this morning to call for stronger protection of the last 55 remaining Maui's dolphins.
About 300 protesters marched to John Key's Helensville electoral office to call on the Government to remove gill nets and stop oil and gas exploration in coastal areas where the world's smallest dolphin lives.
Organiser and chairwoman of Maui's & Hector's Dolphins Education/Action Inc, Christine Rose, said it was a message to Mr Key not just as Prime Minister, but as Minister for Tourism and Helensville MP.
"He was elected to represent the interests of this electorate, and there's a lot of people there from Helensville saying they want this area protected," she said.
Maui's dolphins inhabit coastal areas from Maunganui Bluff to Taranaki, but are concentrated along Auckland's West Coast.
