The 22-year-old is the catalyst who could spark the Hurricanes to life and he's banking on firing when they host the Brumbies at Westpac Stadium in Wellington tonight.
"Our shape is pretty good from an attack perspective," Barrett said. "We've got good systems so we've got a lot more to offer than what we've showed and hopefully the weather's fine for us to show that."
Barrett said the ever-changing scrum laws had put extra heat on teams feeding the ball, meaning attacking from a lineout would give sides better service.
"The lineout has been a strength of ours," Barrett said. "It's operating pretty well so that's going to be where we look to strike a little bit more and step up our game to build phases and also just build pressure."
Hammett's decision to select James Marshall at fullback ahead of the long-punting Marty Banks could be a sign the side will look to keep the ball in hand against a Brumbies team without bruising openside flanker David Pocock, who is out with a season-ending knee injury.
Tearaway loose forward Ardie Savea will again be on the bench but his x-factor could help boot the Hurricanes into life as they search for their first win.
"I don't think the two recent games have reflected how well we have been going off the field," Barrett, who toyed with leaving the Hurricanes last year, said. "We've been building a lot off the field and we've definitely got the week structured how we want it and as players we are responsible for our own roles."
