Mr Greet's qualifications include a masters degree in social work and a bachelor of theology from the University of Otago.
He is a registered social worker and worked for Child, Youth and Family for six years until last July, when he decided he wanted to do something different.
Despite his background, he has failed to get any call-backs from the roughly 70 job applications he has filled out for positions here and in Australia. "I've done social work and advocacy work for years and now I'm doing client advocacy work for the Family Crisis Intervention Service - but I don't get paid for it.
"I've applied to about 60 to 70 jobs and had nothing. Last month I went around some retail stores ... and was told I was over-qualified to stock shelves.
"I just want a job. I want to work."
Kristina O'Neale, 32, has struggled to find full-time work since 2008. She has held several temporary jobs during that time but is trying to get a fulltime role.

"I've been working there ever since. I've been there for a year and it's great. My boss said at the time that he liked that I was showing initiative."
Ms Haffenden was with the group in Manukau.
Employment law advocate Danny Gelb said sometimes employers did not give jobs to people deemed "over-qualified" because they were afraid they would leave early.
"It's like if a rocket scientist was hired as a truck driver. That scientist may not be in it for the long haul," Mr Gelb said.
A spokeswoman from the Human Rights Commission acknowledged that it was not something that came under the grounds of discrimination as set out in section 21 of the Human Rights Act.
