Kaupa added that Moresby North-east has been neglected for the past 5 years because of leaders not working together.
He said he will be working very closely with NCD Governor Powes Parkop and Moresby South MP Justin Tkatchenko to bring tangible service to the electorate.
Kaupa added that the reason for leaving PNG National Party was to work along with Governor Parkop and to develop the electorate.
