Kate Sheppard Cup and Chatham Cup finals are weekend of 6-7 September according to Capital Football - I imagine NZF had little to no choice for the international timing but still it's going to be a juggle to catch 'em all.
At least one Auckland team making each of the Finals would be rather useful for NZF. Could host them up there & have a 'Festival of Football', hoping to drag more neutrals along to the Finals.
