To answer my own question, it's part of the music video of Pokarekare Ana which is one of the special features on the DVD. It does appear he was in a shipwreck although I've got to say, that scene felt a little contrived.
I guess that part of the video wasn't as memorable as Hayley's voice or the cool, glowing magic things she kept finding during the video.
Question answered.
One of my favorite DVDs !
