Starting with an appropriately named "warm-up" game against Northern Territory, given the temperatures will be in the mid-30s, the first international will be against Australia on June 30.
Even with the final World Cup team being named in August, Collier said his and Blundell's inclusion was not a sure sign of a guaranteed berth.
"In terms of the world cup and anything like that, it's a long, long way away.
"By no means am I a certainty," Collier said.
Expecting to bat anywhere from opener through to number six while also possibly trundling his spinners, Collier said the Australians should be similar to the Lincoln series but it will be their first look at World Cup hosts India.
"Over there, you expect more pace and bounce. But we'll be playing on the same grounds so I expect the wickets to deteriorate.
"It could be quite testing in the heat. We're trying to prepare for that with all the fitness tests we're doing over there."
After bowling on Lincoln's slower tracks without reward, Blundell said they will be fit and ready for that sub-tropic environment.
"The temperatures in Darwin will be similar to Dubai, if we do make it.
"We've been picked to do a job and the selectors are trusting us.
"Last series I didn't perform too well with what I should of.
"There'll be a bit of bounce and hopefully quicker to get it through and attack the batsmen.
"Get the batsmen out of their comfort zone, which would be nice."
The tournament had originally been planned to be quadrangular by including England or South Africa.
As a result, the New Zealanders have picked up another interesting game against Papua New Guinea on July 2.
