Police have arrested a second person in relation to the killings of Fuk-Fu Joseph Kwok and Mei Han Chong at their Ellerslie home last Sunday morning.
A 26-year-old man was found at a property in the Auckland suburb of Glenfield on Friday evening and taken into custody, police said in a statement.
He has been charged in relation to both murders and will appear in the Auckland District Court this morning.
On Friday a 42-year old man charged with the murders of the couple appeared in court and was granted interim name suppression.
The man was arrested in Hamilton on Thursday night and will reappear in court on 29 November.

Detective Inspector Scott Beard, from Auckland City CIB, who is heading the investigation, said police were not looking for anyone else in relation to the investigation.
"The investigation team has worked hard to reach this point.
"While arrests have been made, there are still a number of enquiries yet to be completed.
"We can advise the scene examination has now been completed at the Greenhithe area where Ms Chong was located."
A post-mortem on Chong's body is due to be carried out today.
Her husband's body was found in their home on Monday. He had been stabbed several times.
"Police are continuing to provide support to the family at the centre of this tragic incident," Beard said.
Kwok worked as a theatre nurse at North Shore Hospital.
Te Whatu Ora Waitemata operations interim group director Brad Healey said on Friday he was a "respected colleague".
"Joseph was a valued and well-liked member of our North Shore Hospital family and I would like to acknowledge his exceptional service. Our hearts are with those who worked with him. They are feeling this loss immensely and we will ensure they are supported through this period."
