There is a worldwide black market in the collection and export of abalone meat. In New Zealand, where abalone is called pāua in the Māori language, this can be a particular problem. The right to harvest pāua can be granted legally under Māori customary rights. When such permits are overused, it is difficult to police. The legal daily limit is 10 pāua per diver with a minimum shell length of 125 mm. The limit is strictly enforced by many Ministry of Fisheries officers with the help of the police. Pāua 'poaching' is a major industry in New Zealand with many thousands of abalones being taken illegally, mostly undersized. Convictions have caused removal of diving gear, boats and motor vehicles as well as fines and in rare cases; imprisonment. The Ministry of Fisheries expects in the year 2004/05, nearly 1000 tons of pāua will be poached, with 75% of that being undersized.
