Kiwi crashes motorised bar stool on way home from Puhoi Hotel A NEW Zealand man has serious head injuries - after crashing a home-made motorised bar stool on the way home from a hotel. The 62-year-old man had just left the Puhoi Hotel, 50km north of Auckland, on the makeshift vehicle - a go-kart with a barstool on top - when the accident happened on Friday afternoon. Police say he wasn't wearing a helmet and was driving the contraption on the road when he fell, suffering serious head injuries. No other vehicles were involved, police say. ``Whether alcohol was involved will be part of our investigation," Inspector Mark Fergus said. ``The vehicle was not road legal and we've seized it so it can be mechanically examined. ``An investigation is also underway into who actually owns the mechanical bar stool. The man has been airlifted to Auckland Hospital in a serious condition.
