"They're relentless, they just keep going and going," Puawai says.
"We're just expecting really good games."
To prepare for the warmer weather, some athletes have been training in sweat suits, some have been using a heat chamber and they've all been trying to schedule their sessions for the warmest times of the day.
While all teams will be going out on to the field wanting a spot in the finals, and a win, Puawai believes New Zealand's Open Men's team have a good chance of beating Australia.
Carlos Savage, who with Ifor James was selected among the first touch players to represent New Zealand in the NRL Touch Premiership that starts in May, has been part of the Open Men's team for the past three years and Puawai says the squad has only narrowly lost to Australia in previous competitions.
Puawai says the Tauranga players all know each other having played with and against each other. She says touch is a way of life for many of them.
And much like her first time wearing the New Zealand singlet in 2017, Puawai's excited to wear it a third time.
