But by the time Shipstead had landed in New Zealand, she'd found herself at the centre of a news story.
Fans and reporters were messaging her about Swift's whereabouts - even though Shipstead had no idea what Swift was doing at the airport, or where she was going.
"I was starting to feel like someone who has confidently picked a suspect out of a police lineup, only to be confronted with exonerating evidence later," Shipstead writes.
"It certainly was weird and, no, I had not meant for this to happen."
A day later, Swift's New Zealand visit to shoot her latest music video had been confirmed. She has since departed to perform in Australia, but returned to take a road trip around the South Island with her family.
Shipstead said she was in New Zealand as part of a magazine travel assignment, which would take in Antarctica and the Cook Islands.
