This is due to plans to scale down operations.
A notice was issued to all aviation and shipping industries, statutory bodies, corporate entities, stakeholders, NGOs, media and the general public on Monday.
It stated that due to internal matters, the PNGNWS will be trimming down its operational hours from a 24 hour operation to eight normal working hours by 4:06pm, Wednesday, May 3, if its grievances are not met.
Hence, this will promptly shutdown the operation on weekends.
