The owner of a company used by senior Berejiklian government ministers to print taxpayer-funded electoral material despite not having commercial printing facilities has donated nearly $30,000 to the NSW Liberals over the last eight years.

Zion Graphics, a business owned by Bella Vista branch president Rudy Limantono, has been used by Corrections Minister David Elliott to print electoral brochures and other material since 2011.

Treasurer Dominic Perrottet, Western Sydney Minister Stuart Ayres and Mental Health Minister Tanya Davies also used the company to produce material, in 2016 and 2017.

Innovations minister Matt Kean has also used the company, along with several Liberal MPs including Riverstone MP Kevin Conolly, Kuringai MP Alister Henskens and Seven Hills MP Mark Taylor.
