So far this series race organisers have been unable to get through a full day's programme, with the winds building in the afternoon beyond the allowable range.
A change in tidal conditions from today should provide some relief, pushing the tide-adjusted wind limit above 21 knots. But there is still a concern over the reliability of the skittish AC72 catamarans, particularly the Italian boat.
Luna Rossa have experienced breakages on all three of the days, all of which would have prevented them taking part in the scheduled second race of the day had the weather gods not intervened first. Teams can enforce a postponement if gear damage were to prevent them from taking part in the second race, but only have one "postponement card" each.
It is unlikely the Italian team will get through the finals without exercising that option.
With the America's Cup final to be raced under the same format - two races a day over the shorter course - Team NZ will be hoping to experience back-to-back races at least once during the finals series.
Skipper Dean Barker said that although they had simulated the demanding schedule a lot in training, it would help to get a taste of what it is like in a proper race situation.
"All our systems and timing are in place to do that and we feel comfortable with it, but it's still a lot different when you're in a race environment."
Yesterday was unusually quiet at the Cup village with the two challengers doing much-needed maintenance work after three costly days on the water. They'll be back out today for what teams and fans alike hope will be two more races.
