The Institute of Directors hopes to target more people in their 30s and 40s next year as part of a bid to get more diversity on New Zealand's boards.
Chief executive Ralph Chivers said the organisation, which has 5500 members, had just started a second round of a women's mentoring programme but recognised a need for more diversity in age, ethnicity and skills on New Zealand boards.
"Diversity is about much more than gender. It's about diversity of thinking, different careers and commercial experience."
Chivers said though gender was important and the under-representation of women on top boards was not acceptable it should not be focused on exclusively.
He said the institute was looking into helping younger and emerging directors. The current median age of its members was 54.
