About Us

Kia ora! I’m Rhiannon.

I’m the founder of Cassiobury and I am here to help.

Until 2023, I was the CEO of Kiwi Wealth - a KiwiSaver fund manager which looked after over a quarter of a million Kiwis’ retirement savings. At the helm, I built a diverse and high performing senior team, clarified the vision and strategy, divested our corporate start up for $40m, delivered make or break technology projects, experienced operating systems highs and lows, and led the business through the sale process culminating in a $310m exit for its shareholders.

Through my time as CEO, and in my experience leading up to it, I amassed a range of skills and experience which you can leverage as you extend yourself across your own CEO role.

I can help increase your effectiveness so you can deliver more by:

1) Acting as wise counsel. It can be lonely at the top - use me as a high level sounding board and I’ll help you recognise themes, identify anomalies and spur you into any required action.

2) Strategic alignment. So often, I see brilliant strategies and equally brilliant teams - but the two don’t always match and then the strategy/the team fails to deliver. I can distil the existing strategy, stress test and simplify, then help you unite the team around a clear direction, clearing away distractions and setting you on the road to success.

3) Stepping up. Every CEO was once a first time CEO and no doubt it’s a huge step up. With clear goals set by the Chair, I can support, coach and mentor aspiring and first time CEOs using a blend of course material, digitally delivered, and one on one mentoring bespoke to each company’s unique situation.

My skills

I am fast

I sort the wheat from the chaff at speed.

I am direct

I get right to the point. Although being originally from Britain, I manage to deliver most of it politely too.

I am personable

I genuinely like people and it is rare that I can’t find common ground with someone new.

I write well

I won’t write long reports that no one will read but if you need something well written - I can help.

I listen

This is a learnt skill but I can switch it on and learn a lot. I then gather insights which I pass back to you.
