Auckland Airport's investing nearly $150 million into a major domestic airfield upgrade. 

It's part of works to help enable future growth in regional flights across the country. 

Car parks next to the domestic terminal will be shifted to make way for four new aircraft parking stands dedicated to regional services. 

Airports Association Chief Executive Billie Moore told Mike Hosking it's an important move for Auckland Airport, in terms of growth. 

She says 40% of regional flights go to and from Auckland, so the rest of the network relies on them to increase capacity.
