Young Jin Baek, 44, was found dead in the Christchurch suburb of Avonhead yesterday morning, police said.
Police have confirmed he was the husband of Sung Eun Cho, 43, and father of Yeon Jae Baek, 17, known as Holly, and Yeon Sue Baek, 13, known as Kelly, who were found dead last Wednesday.
Police are not seeking anyone else in connection with his death, which has been referred to the coroner.
Mr Baek's wife and daughters were found dead at an Apsley Drive home in Avonhead after Mrs Cho failed to keep an appointment.
Christchurch Korean Society president said last week that Mr Baek lived in Korea, away from his wife and daughters, who had been in New Zealand for about five or six years.
He had arrived in New Zealand last Friday after he was contacted about the deaths.
