"After 20 or 30 years of not having to rely on a benefit, I was suddenly walking into a WINZ office and the shame was incredible," she told Marae.
"The last time I had been in that office I was the local member escorting the Prime Minister through and the staff couldn't believe I was coming in and asking to be signed up for the dole.

"People I used to know in my political life would all but cross the road, avoid me. I hate that about people, I really do."
