"I founded Kōwhiri with the vision to simplify the way trustee and legal services are made available."

Andrew Barnes

Kōwhiri founder

Why choose Kōwhiri?

Kōwhiri exists to ensure every adult can get access to the services they need to protect their assets and estate.

Aging population: what this means for you

Global populations – especially in the West – are aging. This means the largest inter-generational transfer of wealth is now under way. Unfortunately, many people haven’t been given the right information or opportunity to adequately protect their assets – and ultimately, their legacy. When looked at globally, more than half of all adults don’t have a Will. And for those that do, many of these Wills are out-of-date.

Kōwhiri: driving change

To address this very real need we harnessed the latest technology to develop Kōwhiri – with the goal to drive change and improve the way people access the estate planning services they need – either online or by connecting them with the right experts for the right advice.

We believe a digital service, backed by the right people, is the future of estate planning. Our digital service provides your customers with essential education, improved accessibility and quality services. This means it’s now far easier and more affordable for people to establish and maintain an up-to-date plan to protect their precious assets and manage their estate.

Transforming service, delivering solutions

Kōwhiri was founded by Andrew Barnes of Coulthard Barnes and was initially established as part of New Zealand’s largest trust company, the Perpetual Guardian Group.
