Sounds like a prototype has been ditched in the sea. Sounds like the crew are all ok - I really hope so:

Bugger, I guess this wouldn't be the first prototype to come unstuck. I really hope that as indicated, the crew are ok and that the development continues.
Weather in Auckland today is beautiful - clear skies and light winds.
