Kiwi fish are causing a stink overseas.
At the heart of the scandal is the snoek - thyrsites atun - known here as barracouta.
South Africa's City Press newspaper reported Kiwi barracouta was being sold in that country as snoek.
Associate Professor Mafaniso Hara from the University of the Western Cape told the Herald on Sunday there were growing concerns over a lack of transparency. Hara said fish processors were buying the barracouta but just how much was unclear.
"One of the things that we've been grappling with is actually how much 'snoek' is coming from New Zealand."
