About 200 onlookers have gathered on Auckland's Tamaki Drive to watch a pod of orca hunting close to the shore.
Five or six killer whales have been chasing stingrays within five to ten metres of the shore - moving from Okahu Bay, past Kohimarama and towards St Heliers.
Onlookers have been watching what appear to be two adult and three or four juvenile orca throwing stingrays into the air and eating them.
Members of the public have been parking on the side of the road to watch the display but traffic appears to be running smoothly.
New Zealand orcas are the only known orca group that eat stingrays as a staple food, often hunting them into shallow water and sometimes beaching themselves.
Orca Research says New Zealand has the highest rate of orca strandings in the world, about one a year, mostly from hunting errors.
Orcas also eat other foods including fish, squid, dolphins, sharks and seals.
