John Wright's messages seem to be getting through to the Black Caps. They are starting to understand how to play five-day cricket.
I know it sounds a bit stupid, but the key to playing five-day cricket is that you've got to be able to play for five days. That means you've got to be able to bat for long periods of time.
There was a real sense of purpose about the batsmen on that first day. Brendon McCullum and Ross Taylor were the key. Ross played very well late in the day, but both he and Brendon benefited from being patient at the start and being very clear about looking to bat time.
Beating Australia in Hobart has been great for this team. Certainly in terms of the individual players their discipline is improving and their ability to switch from one form of the game to another has also improved significantly. Brendon is a good example of that.
That innings he played on Thursday was out of character for a player who loves to dominate, and came after a steady diet of T20 cricket.
