Competition manager Simon Koima said the forms are available and clubs who fulfilled the registration requirements would be granted license.
"The application for the expression of interest is open today and closes on Sunday 21/08/2016."
"PNG Football Association will issue licenses to clubs who fulfill all the club licensing requirements."
He stressed that only clubs who are licenced are permitted to participate in the 2016-2017 NSL season.
Koima said club licensing was an integral part of building a stronger football programme.
