"It's through training, it's ensuring that people in the call centre are more connected to the markets and they understand the issues and we handle situations with empathy."
The airline was also investing more in training for its cabin crew and airport staff in New Zealand.
"We have a model and that underpins low fares, but in delivering that model we need to bring a lot more [of] that human element to it - the empathy."
Staff should treat customers as if they were friends and family.
Since starting domestic operations here in June 2009, Jetstar's advertising has emphasised cheap and cheerful but Hall said it was time for a broader approach.
"You'll see the brand evolve."
By the end of the year the local leadership team would be comprised of New Zealanders and over the past few months the company has signed collective agreements with unions here for engineering staff, cabin crew and pilots.
Jetstar is releasing special $5 fares this morning to mark carrying five million passengers since launching domestic services nearly four years ago.
The Qantas subsidiary said there would be "hundreds" of the fares on sale from 9am to 10am for travel on its core Auckland-Wellington-Christchurch network for travel in August.
Air New Zealand is today offering 324 $1 grabaseat fares this morning on main trunk routes where it competes with Jetstar for travel during September. On its Nelson to Wellington route it is offering 13 seats at $49 for later this month.
Jetstar's chief executive Australia and New Zealand David Hall said that since domestic flights began it had sold nearly one million seats for $50 or less.
Jetstar now employs nearly 500 people in this country and had expanded its fleet of Airbus A320 aircraft to nine. It flies over 140 services a week.
It was looking at expanding its services here, this year concentrating on its main trunk jet services, he said.
"We're strongly focused on further improving our on-time performance and our customer service standards."
New Zealand's busiest Jetstar destination is Auckland with over 2.1 million domestic passengers since 2009 , Christchurch is second busiest with 1.3 million domestic passengers while one million passengers have flown on the airline out of Wellington.
