The event was witnessed by franchise clubs, sponsors, PNG Football Association, Sports Federation officials and government officials.
When launching the season, NSL chairman Isaac Lupari thanked the participating clubs, franchise owners and Telikom PNG for the support.
Lupari said it had not been an easy journey for NSL in the last 12 years.
"We hope that one day soccer will become the national sport in PNG as it is played throughout the country by all ages and gender," said Lupari.
