all the weekday games in New Zealand better be in the evening otherwise no one will attend. I'm predicting match times to be 17:00, 20:00, 23:00 nz time with NZ having 17:00 and 20:00 and Aus having 18:00 and 21:00, with the last round of group stage and knock out matches being 17:00 and 21:00 (19:00 and 23:00 nz time). Matches need to be late because of EU tv audience and the point I mentioned earlier about weekday attendances
Weekday afternoons might be more attractive than weekday evenings in the middle of winter...
But I think you'll be bang on with the times. The opening night is a double-header Auckland/Sydney, so I think that could be 7pm/10pm NZT or maybe 8pm/11pm NZT. Then the first Sunday is a quadruple header featuring Perth, so expecting that will be 5pm/8pm/11pm/2am NZT.
