So they've enlisted the help of top sailing consultant Dee Smith, who has more than 50 years professional experience, to help clue the team up on the venue.
"This regatta is as much about doing well in the event as it is about understanding the conditions here for next year's Louis Vuitton Cup. This is our last opportunity to sail on the course before then," said Barker.
"We plan to focus on understanding of the venue, the tidal current and the breeze and the tactical situations that arise."
While next year's Louis Vuitton challenger series and America's Cup finals will be sailed in larger-scale AC72 yachts developed by the individual teams, Team New Zealand are targeting a strong performance in the remaining AC45 regattas.
Since launching their first AC72 in July, the Kiwi team have been heavily focused on testing the giant wing-sailed catamaran, with their second boat due in the water in January.
But Barker said the team had to find a good balance between the AC72 development programme and AC45 race training.
"The team organises itself around the AC72 and there will always be a bias towards it. That's the game next year - but we really want a good result at this one," he said.
"This AC45 regatta is the only measure we have right now of skill levels relative to the other teams. It's the last event for some time and it's important for the sailing crew to achieve respectable results."
Ranked seventh in the series standings after last month's poor showing, Team New Zealand will have to qualify for the match-racing finals for the first time, having previously advanced straight through by virtue of their points.
The sailing team had replayed video footage from July's regatta, reviewing strengths and weaknesses of their performance. Barker said the team would also spend some time working on speed.
"We have been struggling a little with upwind speed against the top teams and that gets exposed in this close, tactical racing. We can't afford to give anything away."
