Do NZC actually schedule them though - or is their hand forced by overseas boards that would rather play with the big boys? And when scheduling ODIs (weather permitting) know that they'll get a day's play, as opposed to the fourth and fifth day of a Test?
I can see no place for five match ODIs anywhere in the world. Three max. Even World Cups are becoming increasingly uninteresting.
The fools of the world say Test cricket is in danger but it's actually fast becoming the only format that has meaning. And the only potential spanner in the works is that god awful idea for night cricket to appease the fat cat TV executives.
In saying that, one of the most enjoyable days of my Test cricket viewing life was at Eden Park in 2002 (?) against England under lights. Usman Afzaal completely losing one from McMillan into the stands, Ashley Giles claiming he didn't see one he caught in the outfield (hell of a guess) and just general ridiculous outstandingness. But I wouldn't want it regularly
