Kate Bundle | Chief Executive

Kate has been involved with GRG and its first support group since 1999. Practising as a family lawyer at that time, she represented many grandparents who were raising their grandchildren because of serious issues with their parents.  Through that experience she gained an insight into the plight of grandparents embroiled in the family court system and the challenges they face.

Her career includes experience in various marketing, communications and risk management roles in the banking industry, executive management in the professional development and training sector and editorial work.  

Kate served on the GRG Board as a trustee for 14 years and resigned in April 2015 to take on the communications and business development role for GRG which she held until December 2016 before being appointed Chief Executive from January 2017.

Kate is responsible for the organizational leadership of GRG aligned with GRG’s vision and strategic plan including sector leadership, advocacy, communications, business development and fundraising.  Since 2000, Kate has also been responsible for GRG's submissions on law and policy and the development and production of GRG’s national member summits. 

She graduated with an LLB from the University of Otago in 1989.
Kate and her husband have three children.
