Metiria Turei has confirmed her mother was a flatmate for part of the period she claimed the benefit.
Turei has also admitted to enrolling to vote at the same address as her baby's father - despite not living there - so she could vote for a friend who was a candidate in Mt Albert in 1993.
The MP made the admission in a statement last night, after Newshub published information from the habitation index that showed Turei listed at the same address as her daughter's father, Paul Hartley, in 1993 and 1994.
The index also showed that in 1996 and 1998 Turei was listed at the same address as her mother.
Turei said she did not live at the same address as Hartley.
