The Melbourne couple flew to the Bay of Islands for the event, where they were named the new group's patrons and pledged a US$10,000 ($12,200) donation.
Their connection with the the group came about through Northland orca expert Ingrid Visser's battle to save a young orca, Morgan, from captivity in Holland and now Spain.
Mr Wollen urged those at the launch to "do what you can, not only for the whales, but every living being on the planet".
He recalled his father's screams as his body was ravaged by cancer, and how he had heard the same screams in the slaughterhouse and when he witnessed a harpoon explode in a whale's brain.
"Their cries were the cries of my father. And I realised that when we suffer, we suffer as equals," he said.
Mr Wollen was named Australian of the Year (Victoria) in 2007.
