He will appear in Waitakere District Court this morning.
The names of the women would be released once formal identification had taken place, police said.
Friends confirmed to the Herald that Farhat Rana Malik, in her 50s, and a daughter were found dead by police at the Pooks Rd property, about 10am yesterday.
A neighbour who did not want to be named said he saw a man being taken away by police.
"I came downstairs and there were police all over the road and about three ambulance staff.
"The guy was in the back of the car wearing handcuffs and speaking to the police and ambulance staff who were maybe treating him, too."
Former president of the Waitakere Ethnic Board and friend Ann Degia-Pala said news of the deaths had come as a huge shock.
"It's a difficult time for many friends. [Rana] was known to many people in the community."
Mrs Degia-Pala cried as she spoke about a woman who she described as being "completely selfless".
Ms Malik, of Pakistani descent, was connected to the Ranui Action Project - which organises community events - and was also a member of the Waitakere Ethnic Board and the Pakistan Association of NZ.
Another family friend, the Rev Amail Habib, said he and his wife had met Ms Malik for lunch last week.
"She was a very good friend of ours. She was a wonderful person.
"She loved her family and we were very happy to meet her and spend time with her."
Detective Inspector Greg Cramer said a 55-year-old man, who was known to the victims, made a 111 call to police shortly after 10am, and was at the scene when police arrived.
Mr Cramer said the man was helping with inquiries and police were not seeking anyone else over the deaths.
The bodies remained inside the house yesterday afternoon and police had erected a large blue and white tent in an adjacent yard and removed a section of fence.
