More than $300,000 was paid out over 122 fake policy applications between 2010 and 2013. He diverted $187,036 to Lynch to keep her quiet.
But in 2013, insurance company audits revealed the elaborate fraud.
Lynch was jailed for four years while her former lover was sentenced to two years and three months' imprisonment.
The Parole Board heard last month the Arohata Prison inmate had now come to terms with her offending.
''Until six months ago she did not understand why she was charged and convicted for fraud. However, after reading all the paperwork she now knows that she is 100 per cent responsible for the fraud that she and her victim perpetrated,'' her counsel Andrew McCormick said.
Panel convener Tania Williams-Blyth noted Lynch had incurred a misconduct in March, as a result of which her release-to-work approval was revoked.
She was also reprimanded in May for verbally abusing a staff member.
Despite that, the board did not regard her as a risk to the public.
Lynch accepted she had a problem with gambling and told the board she requested a ''multi-venue exclusion'' which would bar her from establishments with gaming machines.
The Parole Board heard she planned to enrol in a polytechnic veterinary science course and would volunteer at an animal shelter.
While doing so, Lynch would have to abide by a range of conditions until her release date in May next year, and for six months after.
Those conditions included:
• To complete a gambling programme.
• To attend any counselling as directed by Probation.
• To live at an address approved by Probation.
• To inform Probation about any changes to employment status.
• Not to be involved in financial management of any other person, organisation, or business.
• To inform Probation about any intimate relationships formed.
• Not to contact the victim.
• Not to enter any premises with gaming machines.
