"Thanks to the vessel carrying an Epirb, the crew were quickly able to signal to RCCNZ that they were in grave danger and needed help – while the crew of a nearby vessel, who were monitoring the VHF radio, picked up distress broadcasts from Maritime Radio and quickly responded," read the post.
Chatham Island Police sergeant Iain Burns said the pair were commercial fishers out catching blue cod when their 6-7 metre boat flipped.
Fortunately a larger fishing vessel, the Equinox, was just 20 minutes away when the alarm was raised and able to divert to the area and pluck the pair to safety.
The men were brought back to shore but did not require medical treatment.
Somehow their vessel was able to be righted at sea and towed back to Waitangi wharf, said Burns.
He said it was a great result for what could have ended tragically in different circumstances.
"They were pretty shaken up and one had a very minor injury," he said. "Thanks to the Epirb automatically going off when the vessel hit the water we knew they were in trouble straight away. That's the beauty of it and the message we want to get out to boaties."
The Rescue Coordination Centre said the incident, which happened beneath Pt Durham on the southwestern coastline, was a textbook reason why boaties should always carry two waterproof ways to call for help.
The fact the Epirb was registered and its details up-to-date meant emergency contacts were able to be quickly notified by the Rescue Coordination Centre which in turn could help with additional information, the post read.
