"The critical question is...[one] simply of inadequacy of income and issues about poverty,'' he said.
The research was designed to show what areas could be better examined in tackling New Zealand's child abuse levels.
According to CYF's data cited in the research, nearly 20,000 substantiated notifications of abuse were received last year.
A substantiated notification is where the allegation of abuse has been investigated and one or more outcome has been identified. Outcomes include neglect, sexual abuse, physical abuse and emotional abuse.
Professor O'Brien said current policies targeting child abuse were "inadequately informed''
"The fundamental piece is to make sure that we get a comprehensive approach to thinking about issues of child abuse rather than doing what has often happened in recent times which is grabbing at one piece...which might be of interest.
"You finish up asking the wrong questions, if you ask the wrong questions, you always get the wrong answers,'' he said.
The research also showed higher rates of child abuse appeared to be linked with a younger population structure.
This was an area worth exploring, Professor O'Brien said.
The Green Party have also weighed in on the report, saying the Government needed to stop beneficiary bashing.
"Paula Bennett has just introduced punitive welfare policies which put beneficiary families in even more impoverished circumstances,'' Green party Children's spokeswoman Holly Walker said.
"If the minister wants to start turning around New Zealand's horrific child abuse rates she should start supporting families and implementing policies to life them out of poverty, not bury them deeper.''
Ms Bennett was unable to comment on the report as she had not received a copy.
