The last two weeks had seen the players in camp in Wellington and travelling around the country visiting communities far and wide, ahead of a final team summit in Auckland, before today's departure for London.
Crockett said the side has worked hard to maintain their focus, while the recent public relations exercises, such as yesterday's final open training run, had been effective in reminding players about their responsibilities.
"You've just got to keep working hard at training," he said. "The boys have been good, we've still got a lot of stuff to work on.
"The last few weeks, just going around the country and seeing the people in the streets, it's been amazing how much support we've got.
"Everyone's really in behind us and as a New Zealander that's pretty exciting. Having seen this year, with the Cricket World Cup and how the country got right behind the team.
"Definitely as a team we're feeling that support so it's pretty exciting."
