A second person has been charged in relation to the murder of an Ellerslie couple last weekend.
The 26-year-old was arrested in the Auckland suburb of Glenfield on Friday night and subsequently charged over the deaths of Fuk-Fu Joseph Kwok and Mei Han Chong at their Ellerslie home.
Police said the man arrested was due to appear in the Auckland District Court on Saturday morning.
Detective Inspector Scott Beard, of Auckland City, said no one else was being sought in relation to the investigation.
He said a scene examination has since been completed in the Greenhithe area, where 67-year-old Chong's body was located.
"The investigation team has worked hard to reach this point," Det Insp Beard said on Saturday.
"While arrests have been made, there are still a number of enquiries yet to be completed.
"A post-mortem is due to take place this morning," Det Insp Beard added.
What we know about the case
Kwok was found unresponsive by a family member at his Auckland home on Monday evening. He was pronounced dead at the scene by the police.
His death was first treated as "unexplained" but later, a homicide investigation was launched.
Beard said earlier this week Kwok was killed in a violent and brutal manner.
"He died as a result of multiple stab wounds. The nature of some other injuries suggests more than one offender could have been involved.
"We are working to understand why he was the target of this aggressive and unwarranted assault."
Kwok's wife Chong was missing and police said on Thursday it was believed she may be the victim of foul play.
The couple's son, who is in his 30s, told police his mother's disappearance was "totally out of character". Chong did not drive so police said it was likely someone had driven her away.
Police also said evidence inside the house suggested she did not leave voluntarily.
On Friday, the worst was confirmed. Chong was found dead in the Auckland suburb of Greenhithe, with the family's missing vehicle found at an unrelated address in Glenfield with a different registration number.
It was also announced on Friday a 42-year-old man, the first to be arrested in the case, had been charged with two counts of murder. He appeared in the Auckland District Court on Friday afternoon, entering no plea and being granted interim name suppression.
He was remanded in custody to reappear at the High Court in Auckland later this month.
Det Insp Beard said it's still to be established whether this is a targeted attack on the family.
