Greg Marshall and Adrienne Foley, married in Levin on Saturday, played 18 holes of minigolf to decide who would relinquish their surname.
Wearing a bridal dress, Ms Foley had clothing to battle with as well as her husband's form.
The rub of the green went Mr Marshall's way for eight holes, but a hole-in-one on the ninth put Ms Foley back in the game. "The pressure really came on after that."
The action went to and fro at the Foxton venue, but Mr Marshall pulled ahead to a three-shot lead on the 17th hole and clinched it on the last one, she said.
"He got there, he won, so I have to take his name."
