About Us

Leigh Development was founded on the belief that people shouldn’t struggle to find the information they need to run their business or not-for-profit successfully.
There is so much information and support available to business owners and not-for-profits, but unless you know what you’re looking for it might as well not exist.

That’s where we come in.

We provide the support to help you navigate your way through business or with your not-for-profit organisation. We specialise in working with organisations that have an impact focus to their mahi – they want to leave the world in a better place than they’ve found it.

My mission in life is to enable people to create positive impact;

It can be social, environmental, whatever change you want to bring

Sel Leigh, Leigh Development

Kia ora, ko Sel Leigh ahau.
E ngākaunui ana au ki te manaakitanga.

My unique experience from working across private and public sector organisations, has helped to fine-tune my understanding of business processes and the legal requirements that organisations often set aside as too hard.

My ability to connect the dots, source information required and put it into practice simply and effectively can prevent the potential impact of getting things wrong for any organisation.

Our purpose is to achieve positive impact by providing accessible and affordable support to those businesses and organisations that strive to make a difference – where they put sustainability ahead of pure profit; people/planet/purpose first.

Kia ora,  I'm Cat Ryan.

Looking for roles that would work around my children, and that would fuel my fire, led me first to voluntarily running a cricket club. I have played cricket for 30 years, but now I had to teach my self about websites, accounting, marketing and graphic design. These skills led me into the world of charities and incorporated societies.  Once upon a time, clubs and charities could rely on volunteers but the world has changed, and volunteer hours are scarce, and without support, many clubs would fail.

My current roles include sports coach and board member.  My own business has an impact focus of supporting disadvantaged kids into sport. 

I am passionate about working along side others to help them achieve their goals.
