"I just want to get the men thinking more about what they're doing and how they apply themselves," he said.
He wants Whitfield to be "brutally honest" and hopes Sissons, Dodds and others brought into the mix heed the tough talking on what is required from them in the 20 months before the Rio Olympics in 2016.
Brown hopes Whitfield, 39, can come to New Zealand within the next four months for a training camp.
If it has a positive result, he would like to see something more significant develop.
"He's pretty keen on that," Brown said of Whitfield's response.
"We're looking for the right opportunity, then see how it goes, if the guys really respond to him."
Brown reckons Triathlon New Zealand needs to take a creative approach to how it operates.
"Success isn't really all about training. It's a component of that. Look at the winners in triathlon. They're pretty crafty thinkers, guys who are driven and make things happen."
New Zealand's leading women, Andrea Hewitt and Nicky Samuels, had a fine end to their year, with podium places in both the final round of the world series and the grand final in Edmonton six days later to finish third and fifth respectively on the world standings.
They are tracking well for Rio. The men, however, need some help and Brown is on their case.
