Footage of the crash has since gone viral after it was shared on social media and has caused a stir online, with commenters debating whether it was done on purpose and expressing surprise at how suddenly the crash occurred.
The video post has had more than 559,000 views and almost 4,000 comments since it was shared on Greymouth jetboater Kieran Wisdom’s Facebook on Monday.
The footage starts off calmly enough, with Mr Wisdom speeding along in his boat on the Grey River, located in the northwest of the South Island, before he makes a right turn and the boat starts moving closer to the bank where a friend is filming.
At this stage it appears that he loses control of the small boat, which starts to veer side to side slightly.
