"It was really good to check-in and make sure we're in the ballpark in terms of speed, and it seems we are, so we're really happy with that. But days like today really highlight the areas you've got to improve on.
"We've just got to keep focusing on how to make the boat go quicker, make our manoeuvres tidier and get the boat around the race track quicker. And we know all the teams will be focused on that as well, it is about who can improve the most over the next month."
Burling said Team New Zealand, like other syndicates, did not reveal all their cards in their first practice racing session.
"We're definitely not showing all our cards yet, but we feel like we're in a really good space to move forward and improve. We're learning very quickly a few of the things that [the other teams] have been doing really well up here," he said.
"We don't have the boat fully wound up yet, and there's a few things the other guys aren't showing as well, but we're pretty happy with where we checked in. Today has been really positive to say the least."
