Tegel shares have rallied sharply after New Zealand's biggest chicken producer announced it had secured an agreement to export raw poultry products to Australia.
The Auckland-based company said its exports to Australia - worth A$70 million ($74m) in the last financial year, representing market share of 1 per cent - had previously been limited to fully-cooked products.
Australia's total poultry market is worth around A$7.1 billion, according to Tegel.
"This regulatory change opens up significant additional export opportunities for Tegel into the Australian market, although revenue upside cannot yet be quantified," the firm said.
"Tegel will immediately apply for new import permits and looks forward to the significantly increased business opportunities this change will present."
