Fast food giant McDonald's said it will order an immediate audit of fisheries it sources New Zealand hoki from if environmental standards are not being met, after campaigners called on the firm to drop the fish, reported

Earlier this week, a report into New Zealand's fishing industry suggested the country's actual fishery catch was estimated to be 2.7 times more than reported.

Following that report, leaked details emerged of MPI's own investigation into fisheries compliance, dubbed Operation Achilles, which revealed potential illegal discarding of fish by some South Island-based fishing vessels in 2012 and early 2013.
