A NEW ZEALAND CHARITABLE TRUST

Clean water
for communities
that need it.

Good Trust funds water and sanitation projects where we're confident they'll have an impact. As a 100% charity, every dollar you give goes direct to the projects we fund. There are no New Zealand overheads deducted from your donation.

01Why water

Start with water. The rest follows.

Of all the needs in the developing world, we chose one. Mostly because we understood it better, but also because water is upstream of almost everything else - and a water project, once built, keeps giving for decades.

— Food

Crops, livestock, livelihoods.

Reliable water turns subsistence farming into surplus, and surplus into household income.

— Education

A walk replaced with a classroom.

When the daily walk for water disappears, children — most often girls — can stay in school.

— Hygiene

Prevention, not just cure.

Clean water and proper sanitation reduce waterborne disease and infant mortality dramatically.

— Life

The thing everything else needs.

It is not a metaphor. Without it, nothing else we might build for a community can hold.

02Project examples

What your giving actually builds.

A few examples from across the years. We've funded work in South East Asia and East Africa since 2009. Below are some project examples to show how the projects have evolved over time. We've witnessed an incredible maturing of this space. Projects we fund now are incredibly well built, effective and durable.

Latest completed: 2 schools, Kampong Chhnang

Two schools. Safe water, clean facilities, healthier kids.

Our most recently completed project, delivered with our partner Clear Cambodia in Baribour District: BioSand filter water stations, handwashing stations, accessible latrine blocks and waste kilns at two primary schools in Kampong Chhnang. Principals and teachers were trained on filter use and maintenance, so the hardware keeps working long after we leave.

  • 2Handwashing stations
  • 2Latrine blocks — 3 stalls + 4 stalls
  • 2Garbage kilns for school waste management

This plaque is one of them: a BioSand filter and hand washing station completed with Clear Cambodia in 2022. The one below is just for fun: where we started.

Where we started · Hand-dug well · 2011

One of our very first.

This is what the work looked like in the beginning: a village well dug by hand in 2011, with Good Trust funding the materials. We've come a long way since — today most of what we fund is delivered through partners with engineered hardware, BioSand filters and trained Water Committees. The principle hasn't changed: locally owned, built to last.

03What you can do right now

Our next project. Four schools, this winter.

Between May and July 2026, Good Trust is funding School WASH for Better Health — safe drinking water, handwashing stations and waste kilns at four primary schools in Kampong Chhnang province. We're delivering it with our long-standing partner, Clear Cambodia.

05Our story

Two New Zealanders, one quiet idea, 2009.

Good Trust was founded by Andrew Nicol and James Grafas in 2009 — a difficult year for the New Zealand economy, and a season in which we'd both been thinking hard about needs we kept reading about in the developing world.

The idea was simple: find creative ways to raise money and direct it into water projects where it would do the most good. Over the years that's meant straightforward donations, partnerships with businesses big and small, and side projects of our own — like good.music and good.coffee.

We chose water because we understood it, and because we believed it was foundational. Without it there is no food, no education, no hygiene. With it, almost everything else becomes possible.

More than fifteen years on, the same belief still runs the trust. Quietly. One project at a time.
