This is a boon for all those choosing to celebrate the Chinese New Year in New Zealand's South Island, as well as providing more opportunities for travel and commerce, bringing significant benefits for travelers and the regional economy, said a statement of the airport.

For eight years since 2016, The Chinese airline has offered direct flights to Christchurch, with close to 400,000 passengers using the Guangzhou service, it said.
