Cavers who helped in last night's rescue of a Canadian woman who slipped then fell while abseiling down Harwoods Hole on Takaka Hill say the operation went like clockwork.
She was in a party of six - three were still waiting to descend when the accident happened.
The woman slipped about 50 metres and then fell another 10 metres.
She was pulled to the surface just after 10pm last night and flown by helicopter to Nelson Hospital with injuries to her back, leg and arm.
Our reporter Tracy Neal spent the day at the scene.
