David Bain and his wife Liz Davies are expecting a second child, Star Kiwi reports.
The couple, who married in early 2014, had their first child later that year.
In April, it was reported they were selling their Casebrook home and planned to move to Australia.
Bain has also changed his name by deed poll to William David Cullen Davies. Cullen was his mother's maiden name.
Davies declined to speak to The Star.
