Yuen Chun Yu said his airline was aware it was in for a fight on the route but believed there was room for three airlines.
''We know that we have to improve our service to the top standard to be competitive,'' he said.
It had introduced new services including dedicated crew for young children and special rewards for passengers celebrating their birthday such as cakes, cards and access to lounges.  The airline is a full service carrier and will use an A330-200 on the route that will seat up to 259 in economy and 24 in business class.
It is in its 10th year of operation and has grown rapidly.  It added 10 new routes, including Auckland this year.
The first half of 2016 saw Hong Kong Airlines' passenger traffic exceed 3 million, a 12 per cent growth compared to last year.
Yuen Chun Yu said there was potential for the market to grow even further in New Zealand.
