John Mulka profile photoJohn Mulka, Chief Executive

Before joining Blind Low Vision NZ in September 2019, John spent his then 28-year professional working career in the not-for-profit and charitable sector with national organisations in his native country of Canada. He has held senior roles providing leadership to organisations in the areas of amateur sport, at risk youth, disease prevention and a sensory disability. Over his 11 year career with the CNIB (Canadian National Institute for the Blind) his responsibilities grew progressively, culminating with him being appointed as the Vice President, Western Canada in 2015 which he held until accepting the Chief Executive role with Blind Low Vision NZ.

During his time with CNIB John was regarded as a senior member of the Executive Leadership Team and amongst his accomplishments provided oversight to the research and feasibility study of the organisation potentially operating a Guide Dog Program as part of its charitable program offerings. The program was subsequently approved and within an 18 month time period established all aspects of operations and graduated its first working guide dogs for Canadians with sight loss. He also provided leadership to the establishment of CNIB’s rehabilitation service delivery standards and the importance of and use of data to analyse the organisation’s key performance measures and outcomes.

John was born and raised in Edmonton and is a proud alumni of the University of Alberta. John relocated to the west coast of Canada in 1998 due to a professional opportunity and resided in Vancouver since that time, until relocating to New Zealand in September 2019 to join Blind Low Vision NZ.

John’s passions include participating in almost any sport, and also being an avid spectator of major sporting events throughout the year. He also has a keen interest in current events and its impact on the world.
