Unlikely to be 60 additional teams, there were 57 total entries (but only 56 teams listed) in the initial press release. So with 52 or 53 entries remaining, 12 or 11 teams will have byes. Looking at the distribution, I'd say the 8 NRFL sides will have a bye as will 3 or 4 South Island sides. Hopefully this year they pick byes on merit and not by draw.
it was Nelson Suburbs that was missing from the preliminary round graphics, hence 11 teams with byes in round 1.
Sensibly that is the 8 teams in the NRFL. Although not so sensibly that was not co-ordinated with the NRFL draw makers who did not schedule a game that weekend.
Unfortunately the 3 South Island sides that needed a bye were drawn rather than chosen on merit. Hence Halswell, Otago Uni, Roslyn-Wakari get byes when perhaps Coastal Spirit, Dunedin City Royals, and Roslyn-Wakari should have been allocated the byes based on last years league tables. It is that sort of decision making that inhibits the lesser sides entering.
