"Murray has shown great vision and expertise in leading a team to create and grow Vista Group, one of New Zealand's top performing technology companies. His strengths continue to lie in product innovation and customer service and with the diversification of Vista since our 2014 public listing, we want him to focus in the area where he has traditionally provided the greatest value, which is product innovation.
"This is core to the group's success, the heart and soul of what we do," Mr Senior said.
"Now, after more than two decades building and leading Vista Group it is time for him to hand the leadership reins to Kimbal Riley, his natural successor.
"We are extremely fortunate that we will retain Murray's expertise and critical strengths in his new role as chief product officer."
Mr Riley says he is honoured to have the opportunity to be CEO of Vista Group, which is poised for the next stage in its evolution, and he is delighted to be working alongside its visionary co-founder.
The change in leadership is effective from April 3, 2018.
