A cabinet proposal to ban "no-fault evictions" for tenants in NSW, was opposed by ministers who own investment properties themselves.

9News has learned the proposal was taken to cabinet by Fair Trading Minister Matt Kean last year, who was pushing to abolish the right of landlords to terminate a tenancy without any grounds.

It was vehemently opposed by numerous ministers, who believed it impacted the right of a home owner to do what they wished with their property.

Disabilities Minister Ray Williams was one of the most vocal in pushing back on the plan. Mr Williams lists six properties on his public register.

Environment Minister Gabrielle Upton has five, Racing Minister Paul Toole lists four while Tourism Minister Adam Marshall has three.

Minister for Women Tanya Davies, Finance Minister Victor Dominello and Correctives Minister David Elliot have also declared they invest in property.

9News does not suggest all of these ministers vocally opposed banning no fault evictions in cabinet.

When asked if these ministers disclosed their property interests to their cabinet colleagues before debating the proposal, only Mrs Davies addressed it.

"I meet disclosure requirements... including during cabinet deliberations. " A ministerial spokesperson for Mrs Davies said.

All other ministers refused to comment on cabinet, but insisted they had adhered to their obligations by publicly declaring their properties.

Under the NSW Ministerial Code of Conduct, a conflict of interest can arise where a decision may result in a private benefit. 9News has been told Premier Gladys Berejiklian is comfortable this does not meet that criteria.

"It's a conflict of interest if you own an investment property and you are making laws about investment properties." Opposition Leader Michael Daley said.

A review of tenancy laws introduced to parliament in September saw changes which include rent increases limited to once a year for periodic leases and set fees for breaking a fixed term lease.
