Maori business consultancy group Poutama Trust is encouraging exporters to test their food safety procedures in light of the Fonterra milk contamination scare.
China has put a temporary ban on some Fonterra products as work continues to trace goods which may contain contaminated whey protein.
Poutama Trust chief executive Richard Jones says there are concerns the incident will damage New Zealand's reputation for food safety.
He advised Maori exporters to check and test their food safety procedures, traceability systems and risk management to relieve any fears its Chinese customers may have.
It is likely many will be making contact with their Chinese counterparts to re-build trust and strengthen the supply chain, Mr Jones says.
