What they need to do is:
1: ask for a side to nominate to fill the spot in NPL2, having a bye is just ridiculous at that level.
2: ZL1 champ doesn't have to go up if they win the comp, it should be option.
3:Last in NPL2 does not get relegated if this happens.(if they choose to drop down, it goes back to option 1.)
4: promotion between ZL comps as per usual.
