"As the business case is still being finalised, we're not able to provide more detail at this stage.
"However, what we can say at present is that there are two key areas of focus for Rotorua."
Mrs Chadwick said the first was making sure the proposal would be commercially viable and sustainable in the long-term for everyone involved - including the local community, council, airport, airlines and others.
"The second key area of focus is to attract air services that more effectively link us with the South Island - and Queenstown in particular. Rotorua has made it clear that this direct link is critical for tourism and economic development purposes.
"This will continue to be a priority in discussions with both Jetstar and Air New Zealand."
Mrs Chadwick said ultimately the goal with any airline was about increasing capacity and that was something it had been able to achieve with Air New Zealand recently.
She said Rotorua had a long history with Air New Zealand, and it continued to demonstrate commitment to the region with increased capacity.
"We want to be supportive of any airline coming into Rotorua, and the most important demonstration of public support is always going to be the one that is shown by bookings."
Mrs Chadwick said Jetstar would make its decision on how well the business case stacked up for it.
"Equally, we have to ensure any such arrangement also stacks up for Rotorua."
