A Korean fugitive accused of killing three family members has been arrested by police in New Zealand.

The 35-year-old is suspected of killing his mother, stepfather and 14-year-old half-brother in South Korea on October 21 before fleeing to New Zealand with his wife and two young daughters.

He was arrested at 5.30pm today by New Zealand police on a separate historic theft charge, and is now in custody.

The man is due to appear in North Shore District Court tomorrow.


"New Zealand Police are continuing to liaise with Korean authorities and this matter is being treated as a priority," Detective Senior Sergeant Nadene Richmond said in a statement.

"Extradition proceedings have not been received, for that reason, police cannot add anything further at this stage."
