He was trying to have a fun run in the sun - until someone jumped on his back and ruined his day.
That someone was Sam Morgan, who has a new show on WatchMe called Sam's Mischievous Life in which he tracks, and then pranks, unwitting Kiwi celebrities.
His first target was Green, the star of The Bachelor New Zealand, who he found jogging around Victoria Park on a sunny day.
Morgan jumped on Green's back and was carried a short distance before being thrown to the ground.
As Morgan sprints off with his cameraman behind him, Green watches them escape with a look of bewilderment on his face.
At the end of the video, Morgan said Green had agreed not to press charges as long as he plugged his new book.
He promised to prank Green's partner, Bachelor winner Matilda Rice, for his next video.
The series is part of WatchMe's stable of free shows, including Critic and the Pig, Late Night Big Breakfast and The Civilian.
