Mr Marriner said tourism turned Kaikoura around in the 1980s through the iconic whale-watching business.

"It's a well known story throughout New Zealand and tourism and hospitality here in Rotorua can help maintain that story, but maybe add a new chapter of support.
"Whale Watch Kaikoura, like Zorb New Zealand is an iconic tourism brand, we know they would do the same for Rotorua if the roles were reversed."
Kash4Kaikoura is being supported by Base Backpackers Rotorua and Taupo, Rotorua Top Ten Holiday Park, Peterpan's Adventure Travel, Sobar, Downtown Backpackers, Kaitiaki Adventures, The Agrodome, Agroventures Adventure Park, Ponsonby Rd Lounge Bar, MacPac Rotorua and Zorb New Zealand.
Any local businesses keen to get on board are more than welcome and just need to make contact with Zorb New Zealand directly.
Mr Marriner said the campaign was phase one of a two-phase campaign to raise much-needed funds and supplies, with phase two being Kans4Kaikoura - which will aim to gather non-perishable goods to be sent down.
All proceeds will go to the Cross Roads Trust Marlborough.
Trust spokeswoman Jannette Walker said workers in the Kaikoura tourism industry were not looking at short-term losses, but a long and slow recovery.
"Any support given from Rotorua's tourism industry will be greatly appreciated by the communities down here as it could take months and even years to restore confidence in the destination," she said.
