"Reports that the service at the Wellington end is heavily incentivised by WCC and Infratil (the airport owners) so will be interesting to see how long this lasts..."
$9NZ$ per passenger and the deal is signed for 10 Years. The money comes out of a fund which is there to bring new business to Wellington, so no extra cost to rate payers.
Once the daily service starts the amount will be less anyway.
This amount is less than Jetstar is getting!
