Mrs Mattock said some people outside the rink jumped on to the ice to assist her. "They lifted her up and we could see the blood on the back of her head and on the ice."
She said she was shocked there was no first aid staff helping the lady and little done about the blood on the ice, with people skating over it.
Ice World New Zealand event manager Robert Ahchee said they always had at least one first aid-trained staff member at the rink.
