A day at the races watching - and punting on - McCullum’s horse Defibrillate will be apt preparation for this England, a team playing with a level of joy and confidence only winning will engender.
Along with a bit of cricket - they cracked 465 runs from 417 balls on day one of their pink-ball tour match against the New Zealand XI - the tourists have been treated well by their local guide.
England began their stay in Queenstown and, together for the first time since their historic sweep of Pakistan in December, the focus has been on fun - and golf.
“Some good golf, some bad golf, and everything in between,” McCullum said. “We were at the Millbrook Resort, which was lovely, so we were able to be away from everyone and just spend a lot of team time together.
“I think with split formats now, it’s really important that you give yourself some time to be able to embed those relationships and get the banter going again; and just get the guys relaxing their shoulders and getting back into touring life.
“We’ve had a good week or so with the boys now - being able to take them around some of the good spots in New Zealand and show them some of this country - and it’s been great to spend some time together in a relaxed environment. But also now we’re starting to turn our attention to cricket.”
That could be bad news for the Black Caps, whose last test series against England ended in a 3-0 away defeat during McCullum’s first assignment.
The rookie coach is expecting a different challenge in New Zealand conditions, but if form and mood are any indication, only one side will find much fun about over the next few weeks.
