There is excitement about the discovery of a whole range of unknown marine species off the Northland coast of New Zealand.
The Department of Conservation has been using a remote-operated camera in the Poor Knights Marine Reserve. It can survey depths of up to 300 metres.
Marine scientist Dr Debbie Freeman says very little is known about New Zealand marine life at depths below 40 metres so the technology opens a new frontier. She says they have found a tropical fish never seen before in New Zealand waters, a new sea slug, and other sponges and organisms which they have no idea what they are.
