A T rex fossil and a papier mache polar bear will join a climate parade down Victoria St on Sunday.

The representatives of global warming will accompany the crowd down Hamilton's main street as part of an international effort to raise awareness of climate change and climate negotiations in Paris in December.

Organised by Waikato Climate Action, the parade is part of the global People's Climate Movement, which will see thousands of New Zealanders march in 30 centres around New Zealand on Saturday, November 28.

"We are calling for a policy on climate change that we can be proud of," said Robert Moore, Anglican Action's representative on Waikato Climate Action.

"We want Aotearoa New Zealand to be a responsible global citizen and we want the Waikato to be a responsible region."

Forest and Bird, which will have representatives at the event, has warned that Waikato and Bay of Plenty risk losing native animals such as the dotterel without meaningful action from the Government.

"There are only 2000 New Zealand dotterel and they depend on nesting sites in Waikato and Bay of Plenty regions," central North Island conservation manager Al Fleming said.

"Dotterel are very susceptible to sea level rise, as they nest just above the high tide mark and are often taken out by storm events and tidal surges. Without committing to a bold climate target, this iconic bird moves closer to extinction."

Waikato Climate Action is a community group tasked with keeping climate change conversations alive in the Waikato. It's made up of environmentalists, academics, faith leaders, community organisations, unions, businesses and health professionals.

Hamilton Mayor Julie Hardaker has been invited to speak at the parade. Hardaker recently signed the Local Government Leaders Climate Change Declaration, a document that calls for urgent and ambitious climate change policy and action.

The parade will begin with a karakia at 11am at Garden Place.

It will end at the band rotunda at the south end of Victoria Street, where there will be a picnic and displays from a range of organisations.

The giant T rex fossil was developed by local arts advocate Mark Servian and the life-size polar bear by local artist Edward Hunia.
