Whale Watch Kaikoura says it's too early to say when the famous tourism business will be on the water again.

The award-winning business said with roads blocked to the town, damaged infrastructure as well as water depth issues in the marina it was too early to say when the team would be back.

General manager Kauahi Ngapora was grateful for the support and understanding following this week's massive quake.

"My thanks and tautoko go to all those who have been affected, and to those who have done what they can to help our community and others that have been severely impacted by this disaster," he said.

"Our priority since the quake has been our whanau, staff, visitors and community and to do what we can to support them at this time."

Ngapora said whanau and the health and well-being of those affected had been a primary focus.

"Kaikoura is a town of incredible resilience and character and we will come back from this.

"In the meantime my team and I will continue to do what we can to support and help get our community and our whanau and friends back on their feet."
