While they are expected to have a significant edge in terms of boat speed, Team New Zealand have previously been less than convincing in light breeze - a strength of the Italian challenger - and something skipper Peter Burling addressed at the opening press conference on Tuesday morning.
"I think we've made pretty big gains across the board, but probably especially in the lighter airs," said Burling. "The light air was probably our most perceived weakness in the Christmas Cup but now it's been something that we really feel like we've made some pretty massive steps forward in that area. We're pretty happy with our performance in that area now."
Burling and Co showed their progress when out training later in the day - on the same course racing will take place today and in light air.
According to videographer Harry Lusk, Te Rehutai appeared "very stable" in about 7-9 knots south-westerly, just above the 6.5 knot lower wind limit for racing in the America's Cup.
"The afternoon started with very light winds but increased as the day progressed. She appeared very stable in these conditions," Lusk posted on his YouTube channel.
Sailing fans were quick to comment on the performance, with one poster calling the performance "phenomenal".
"If LR (Luna Rossa) are faster than this in these 'drifting' conditions, then they deserve to win. This looks phenomenal."
The teams started the America's Cup early with a impromptu drag race on the Waitematā Harbour last Thursday - again with Team NZ looking the faster of the two boats.
When asked to reflect on their body of work over the last three years, Burling left no doubt about their priorities and focus.
"We've done everything we can to try and get the fastest package possible and in more recent times it's been around making sure we don't have any massive downsides to that.
"But you know looking across the way, the Italians have put together a pretty nice package as well so that's what makes it all the more exciting come tomorrow."
