Not just ZL2/3, all ZL1 matches last week had 2 officials for all 3 grades, 1 ZPL match had only 2 officials for all three games, and some other 3rd grades only had 2 as well.
Problem is the numbers, and unfortunately, due to the abuse that refs have copped over the years, a lot of them have had enough, as well as being over worked by northern, but that’s another issue altogether.
