NIWA scientists have discovered that nearly all snapper on the west coast of the North Island come from nurseries in just one harbour.
Snapper is New Zealand’s largest recreational fishery, and one of the country’s largest coastal commercial fisheries with an annual export value of $32 million (2008).
But in recent years some stocks have failed to recover from historical overfishing, with some commercial catch quotas for snapper being cut recently to protect the species.
