When the second division starts up - will Kiwi's count as inports - will they have an import rule?
They do in the NPL afaik, so I would expect that to be the case
A prime reason to set up the NSD, is a belief not enough young Aussie talent is getting a crack at the ALM. So yes expect Kiwis to be treated as visa players.
But NSD clubs will be operating on a fairly tight budget, so I expect some of the better NZers in the NPL leagues will be signed up. Is still no guarantee a national NSD will actually happen yet. Could like the NZ National League, just end up an end of season playoff system of qualified clubs from the various state NPL leagues.
