New Zealand Trade Minister Tim Groser is to meet his Indonesian counterpart to try to resolve a standoff over halal beef exports.
Indonesia has reportedly held up shipments of meat from New Zealand at its ports over their halal status. It is considering banning meat from Australia also.
Indonesia imports an estimated 70,000 tonnes of beef from Australia and New Zealand every year. All beef imports have to be certified halal by Muslim agencies in New Zealand.
Indonesia says it blocked the shipments after a Muslim clerical council reviewed slaughterhouse certificates and found they had expired.
Indonesia's agricultural minister has been reported as saying New Zealand and Australian face a total ban on beef exports if they don't have all certificates renewed by October.
Mr Groser is scheduled to arrive in Indonesia early on Sunday (NZT) for scheduled talks. His staff say he will push the issue at a meeting on Sunday or Monday.
The New Zealand Meat Industry Association says there has been no official notification from Indonesia of any trade problem.
