The Oracle support boat then dutifully followed Aotearoa into the Great Sound, capturing more shots and footage.
Team New Zealand seemed unperturbed by the surreal situation.
That's probably because the Kiwis are hardly holier than thou.
Team New Zealand has been doing the same thing, assiduously gaining as much information as possible to determine whether Oracle are capable of a San Francisco-style comeback.
Ray Davies told Newstalk ZB's Rachel Smalley that the team continues to keep a close eye on Oracle.
"They're sort of changing their boat to look a little more like Team New Zealand's, so that's very interesting."
And TNZ performance coach Murray Jones told the Herald that Oracle have "been playing around with several different configurations with their rudder elevators, and also their boards.
"They've been doing a lot of work changing a few things closer to how we sail the boat.
"I guess these last couple of days is just assessing those changes and I would expect on Friday to lock it in and get used to sailing the boat again in a slightly different configuration."
Spying, it seems, is now routine fare.
