A number of people have been injured during a series of vampire-like biting attacks on New Zealand’s North Island.

Over the past two days, a woman was accused of biting a man’s neck so hard, her teeth cut through an artery, while another woman was arrested after allegedly chomping on a woman’s ear.

Stuff.co.nz reports the two incidents on Saturday and early Sunday were unrelated.

“It was a fight between three females and during the fight one of the females has bitten another one’s ear and drawn blood. She hasn’t bitten it off, but quite badly so she needed some medical attention,” a Hawke’s Bay District Command Centre spokesman said of the first incident.

A few hours later, police were called to a separate biting attack at a pub in Napier, New Zealand.

Officers said a woman became involved in a brawl at The Thirsty Whale and bit a man on the neck.

The man lost so much blood, he was taken to a hospital in serious condition, the Hawke’s Bay District Command Centre spokesman said.

“She obviously got the right spot.”

Thirsty Whale bar owner Chris Sullivan said the fight took place in the early hours of Sunday.

“We’ve never seen these people before, they’re certainly not locals,” he said.

“It’s a very nice area. We’re a restaurant, we do have a dance floor on a Saturday night, but we have nice people … people having a great time. But a couple that night clearly didn’t.”

Earlier in the week, another person was bitten during a family violence incident.

“It is a little bit weird,” the police spokesman said.
