Achieve the 


you want

to make

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 is to enable people to create positive impact;

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

– Sel Leigh, Leigh Development

E ngākaunui ana au ki te manaakitanga.

I used to judge my value by how busy I was.
What that really means is, that I used to judge my worthiness by how much I did for other people and not for myself.

Of course, the inevitable happened and I burned out.

And you’d think that would have been my lesson learned. But fast forward a couple of years and the same thing happened again. This time I took the time to learn from it.  I took my background working across government and in private business, and everything I knew about running not-for-profit organisations and transformed my business.

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.

I removed my potential for future burn out and I’m now helping others to do the same.

If you’re constantly juggling your commitments and feeling overwhelmed or worried about breaking things, do you need support to break the cycle before the breakdown?

Cat smiles up at the camera

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 had 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 alongside others to help them achieve their goals.

Our Values

What we believe

Diversity, equity and inclusion are our building blocks

Human rights for all. Dignity, fairness and respect. We challenge inequity by pushing against the status quo and systemic marginalisation and we support others to enable them to do the same.

Be a bloody good human. Simple.

Community led development is critical to change

We are a tangata Tiriti organisation that recognises te tino rangatiratanga of hapū as expressed in He Whakaputanga o te Rangatiratanga o Nu Tireni and as affirmed in te Tiriti o Waitangi.

What this means is that we will pull out all the stops to ensure that we will do what is right by Māori as tāngata whenua of Aotearoa, and as was agreed to in He Whakaputanga and te Tiriti o Waitangi. We do this because we believe that what is good for Māori is good for everyone, and we believe it is our responsibility to help disrupt the narrative to the contrary.

We champion diversity and inclusivity practices, and actively promote and support working with other organisations that demonstrate positive engagement with whānau/hapū/iwi.

What this does not mean, is us representing ourselves as experts in cultural competency.  We guide, but we do not instruct.  In all cases, we will defer to the voice of lived experience and we will advise you to do the same.  Consultation and co-design mean to extend the invitation to plan the party, not attending it after you’ve decided on the theme.

Lead with curiosity, couple it with humility.
