"This is a big event for us as we can lock down that Olympic spot," said Tyack.
"And getting one of the last three spots in the team event in Utah later in the year isn't beyond us either.
"There are quite a few strong teams who still haven't booked a spot in London, but that doesn't mean we can't get one of them.
"Our best is up there with the best of them and we've shot scores as good or better than some of these people.
"It will come down to how our form is on the day."
The other members of the Australian men's squad competing in the Oceania qualifying round are triple Olympian Matthew Gray and reigning US Open champion Taylor Worth.
Elisa Barnard, Alice Ingley and newcomer Odette Snazelle will be contesting the women's event in Masterton.
The vastly-experienced Deonne Bridger will not be making the trip to New Zealand, although she remains right in the mix to qualify for a third Olympic campaign in London.
