From Consumption to Guardianship: Rethinking How Tourism Uses Our Natural Resources
Most pools hold water, Wai Ariki draws it from the land and returns it daily – here’s why.
Wai Ariki a sustainable geothermal spa experience in Rotorua
Most pools hold water. At Wai Ariki Hot Springs and Spa, we draw it from the land and return it, every day.
Environmental stewardship and the sustainable use of natural resources are becoming increasingly important in tourism. Today’s travellers are more conscious of their impact, actively seeking experiences that care for the environment and respect place.
Water is often taken for granted even in leisure spaces. A standard pool in New Zealand holds thousands of litres, requiring constant energy, chemical treatment, and replenishment to maintain.
At Wai Ariki, a leading geothermal spa in Rotorua, we’ve taken a different approach.
A regenerative approach to geothermal wellness
Across our 13 geothermal pools, each one is drained and cleaned nightly. The water is returned to the whenua (land) , and fresh geothermal water is drawn for the next day’s use.
It’s a cycle designed to work with nature, not against it.
“Finding sustainable ways to operate is key in a world where we are constantly taking too much,” says General Manager Debbie Robertson. “Our region is fortunate to draw on geothermal energy from our whenua and we use that resource with care.”
“Most pools try to hold water in place for as long as possible. We’ve taken a different path creating a continuous, regenerative cycle.”
A natural cycle, guided by te taiao
Each day begins with fresh geothermal water drawn from deep within the earth through natural wells — a direct expression of te taiao, (the natural environment).
Naturally heated underground, the water is delivered to Wai Ariki before being cooled to a comfortable bathing temperature for our manuhiri.
At the end of each day, the water is released from the pools and reinjected deep into the earth. From there, it continues to circulate through Rotorua’s geothermal system, helping protect the long-term sustainability of this taonga.
This take, use, return to whenua model sets Wai Ariki apart as a sustainable spa in New Zealand.
Grounded in kaitiakitanga
Our approach is shaped by the practices of our tīpuna and our responsibility as kaitiaki of the whenua.
“As kaitiaki, we believe that what we take from Papatūānuku (earth Mother), we return to her in its natural state,” says Robertson.
Globally, most water systems follow a linear model take, use, dispose. Wai Ariki shifts this thinking toward a circular, regenerative system that supports both the environment and the experience.
Pure water, authentic connection
Our geothermal water is rich in minerals and contains only silica with no chemical additives.
Keeping the water in its natural state allows for safe reinjection into the earth while also delivering a premium bathing experience. The result is clean, naturally balanced water that reflects its source and enhances your connection to place.
For visitors seeking a Rotorua hot springs experience that is both authentic and environmentally conscious, this makes all the difference.
Sustainable luxury, thoughtfully designed
Our use of geothermal energy extends beyond water.
Pools, saunas, and heating systems have been designed to maximise efficiency, with geothermal resources providing naturally heated water, underfloor heating, and indoor climate control. This significantly reduces reliance on artificial energy sources.
“Our goal was to show that luxury doesn’t have to come at the cost of the environment,” says Robertson. “By integrating geothermal energy across the site, we reduce energy use while still delivering a premium experience.”
Looking ahead
As global travellers increasingly seek eco-friendly travel experiences in New Zealand, tourism operators are being called to think differently about how natural resources are used.
At Wai Ariki, our commitment goes beyond sustainability it is about long-term kaitiakitanga (guardianship), ensuring that these natural resources are protected for future generations while continuing to support meaningful visitor experiences today.
