Christchurch and Canterbury Tourism chief executive Vic Allen says the airport, hotels, conference venues, visitor attractions and car and campervan rental companies were all operating as normal.
He said damage in the Christchurch central district appeared to be minimal, although building assessments are still being carried out.
"Christchurch is now one of the safest cities in the world, following our infrastructure rebuild and strengthening upgrades," he said.
"We are encouraging people to keep their plans to come to Christchurch."
However, north of Christchurch, the popular visitor centres of Hanmer Springs and Kaikoura are currently inaccessible by road and rail.
