Many of Christchurch International Airport’s claims about a possible airport at Tarras are false, according to a group called ‘Informed Leaders’.

The group of researchers and scientists concerned about the proposal for a new international airport in Central Otago wrote to the project’s shareholders this week with “significant concerns” in response to the feasibility study the airport company shared last week.

The letter highlights six “unsubstantiated claims or assumptions” the airport company has made, Informed Leaders spokesperson James Higham said.

James (a distinguished professor of sustainable tourism at Griffith University and honorary professor at the University of Otago) said the information was “very concerning”.

“We are certain that there is significant unacceptable risk for [Christchurch International Airport Limited], its shareholders and therefore ratepayers, as well as the people of New Zealand.” 

In the letter (which was also sent to the prime minister, relevant ministers and Christchurch City councillors) the group said there was an “imbalance, bias and predetermined view” in the airport company’s public communications about the project, and an absence of existing science and research. 

Assertions that Christchurch Airport is a world leader in carbon management and claims that the aviation industry is on its way to zero carbon are false, Informed Leaders said.

“Not only is their communication largely devoid of reference to rigorous supporting evidence, but many of its assertions and conclusions are contrary to scientific insight,” they said.

The group also highlights similar concerns to those shared by local Regional Tourism Organisations (RTOs) last week about over-tourism.

Lake Wānaka Tourism and Destination Queenstown said the development of an airport in Tarras is not aligned with the new regenerative tourism approach in the Southern Lakes.

“The need to manage future growth, rather than submit to it, is completely lost in CIAL’s plans,” Informed Leaders said. “The numbers CIAL presents do not fit with a sustainable future or economy, nor with tackling climate change.”

The 79 researchers, scientists and associated professionals that make up Informed Leaders say the airport project should not go ahead.

“In our view, the significant financial risks alone associated with this project are enough that it should be shelved, as those risks will ultimately fall on the people of New Zealand, and specifically our children and grandchildren. 

“These risks include the burden which will come as the costs of carbon increase. But there are also others.”

James said Informed Leaders had offered to brief shareholders and stakeholders about their concerns based on existing, peer reviewed research insights. 

They are meeting with Christchurch City councillors for a second time later this month.
