Cartilaginous fishes have low productivity and are vulnerable to over-fishing, but a lack of data means that stock assessments are rarely possible. To address that limitation, this report performs indicator analyses for New Zealand blue, porbeagle and mako sharks. There was no evidence that the stocks of these sharks in New Zealand waters have been adversely affected by fishing at the levels experienced since 2005, and there are good signs that they are increasing.
