An uptick in premium travellers is also been seen through the airport.
"We've seen that across all of our airlines. It's constant feedback we are getting through Emirates, through Singapore Airlines for United Airlines, Cathay Pacific, and China Southern. So they are filling the front of their plane," said Cribbens.
She said they are seeing it so strongly, United Airlines has increased capacity on their larger aircraft to fulfil that demand.
In June, Ministry of Business Innovation and Employment announced the government's Tourism Growth Roadmap. The strategy included a long-term plan for the tourism sector, and how it was going to increase it's value.
The end of stage one is set to be completed by 2026, with the goal to return overseas visitor numbers by pre-COVID levels at least (3.89 million).
To reach this, the roadmap gave Tourism New Zealand $13.5 million for international marketing in our core markets of USA, China and Australia. $6 million was given to target emerging markets like India and Southeast Asia. $3 million was given to boost business events.
Tourism New Zealand told Metro News the funding allocation was "not designated to one campaign, but is being used to fund a range of activity across our markets."
They said the funding was intended to bolster new and existing campaigns across the core and emerging markets.
The 100% Pure New Zealand global campaign, and partnerships with celebrities from India and China, have made up parts of the funding so far.
Cribbens said any investment is great, however said there were "many factors that play into making a season of success."
"That comes down to airlines and their capacity, so we've been really fortunate that a lot of our airline partners are starting to get aircraft back, and they're choosing to put that down in Christchurch.
With those core markets bouncing back post-COVID, Cribbens said the funding puts New Zealand on a silver platter compared to other countries.
Watson hoped some of the investment would boost Christchurch further.
"We often say if you haven't been to Christchurch in the last five years, you haven't been to Christchurch. It is a new city.
"Most of the tourism images that are used offshore are actually of the South Island, so we need to do more and more to draw people into Christchurch and into the South Island."
