Burling said their crews inconsistency in race six was down to the lack of time on the water the last few days.
"It's been a few days since we've sailed in this breeze so for ourselves we're going to do a little bit of sailing off the course here now. I think for myself in that second race, we definitely missed a few shifts and definitely a lot to conservative in the start," he said.
"In that last race we knew what we had to do to win and I think the guys did an amazing job to get the boat around the course."
Team New Zealand will face either Artemis or Dean Barker's Team Japan in the final - with the winner advancing to face Oracle Team USA in the America's Cup final.
Artemis look the likely opponent after sweeping Japan in all three races today to take a 4-3 lead. They will return to the water tomorrow but with strong wins forecast there is a chance sailing will be cancelled with Artemis advancing.
