The airline has been negotiating with the Kāpiti Coast District Council for months, after Air New Zealand stopped flying the route to Auckland.
The council agreed to support Air Chathams through the 'Fly Kāpiti' campaign, which includes a $50,000 marketing investment, which Air New Zealand with be matching.
Kāpiti Coast Airport, which is owned by Todd Property, has also offered Air Chathams a free terminal lease for the first year, along with other ongoing discounts on operating charges to support the successful start-up of a new service.
"We would like to acknowledge the support we have received from these organisations. They have all worked hard to offer substantial support, to ensure that a direct service from Kāpiti to Auckland will resume," Emeny said.
Mayor K Gurunathan thanked the many players involved in attracting an airline back to Kāpiti to offer this direct to Auckland service.
"From the minute it was announced Kāpiti flights were being withdrawn I told Kāpiti to 'watch this space'. Now all the hard work with business, community and government to rally support to attract and secure air services for our district has paid off.
"The future economic development opportunities the link offers Kāpiti are significant.
"We have a buoyant district economy and the ability for people to fly the Kāpiti to Auckland route really strengthens business, family and visitor connections and will bolster our visitor economy.
"We know from our conversations with passengers on the previous service that the convenience of this direct route from Kāpiti is a big part of people's decision-making when choosing to fly from our local airport."
Established in the mid-1980s on the Chatham Islands, flying live crayfish to the mainland, Air Chathams is New Zealand's largest privately owned airline, operating more than 80 flights per week between Auckland, Whakatane, Whanganui, Wellington, Christchurch and the Chathams.
