Te Aroha Mineral Spas

What to expect

Te Aroha is a small Waikato town that was once one of New Zealand’s busiest spa resorts, and the old spa grounds are still in the middle of it. Te Aroha Domain sits at the foot of Mount Te Aroha, a park of Edwardian bathhouses, lawns and paths. The Matamata-Piako District Council calls it the most intact Edwardian spa in the country. Te Aroha Mineral Spas is the working bathhouse inside it.

This is not an open pool. You book a private room for 30, 45 or 60 minutes. Each room has a wooden tub, a changing area and an ensuite, and you can adjust the temperature yourself during your soak. A buzzer tells you when your time is up. It is quiet, simple and good value, and it feels more like a traditional bath than a resort.

The water is the reason to come. It is hot soda water, naturally carbonated, and it has a soft, silky feel. It comes from the Mōkena Geyser, a few steps from the bathhouse. The operator says the water leaves the geyser at about 198°F92°C and is cooled with town supply water, with no chemicals added.

The Mōkena Geyser

The geyser is a sight in itself. Regional tourism body Hamilton & Waikato Tourism says it was created when a bore was sunk in the 1930s to improve access to the soda water, and that it erupts roughly every 40 minutes. The district council describes it as the only hot soda water geyser in the Southern Hemisphere. It is named after the chief Mōkena Hou, who gifted the land around the springs. Watch from the path beside it; the water is boiling.

Bookings are essential, especially at weekends. Book online through the operator’s site or call 07 884 8717. Massage and beauty treatments are run separately at Domain House Beauty, in the historic Domain House at 14 Wilson Street, about two minutes’ walk away. The operator suggests soaking first and leaving 30 minutes before a treatment.

Rules and etiquette

• No solo bathing. At least two people in every spa room. This is a firm safety rule.
• Time limits. When the buzzer sounds, you have 10 minutes to dress and leave. You may be charged for running over.
• Keep the water clean. No soap, shampoo, beauty products or exfoliants in the tub. The operator may charge you if food or products spoil the water.
• No food, smoking or alcohol in the spa. Intoxicated people are turned away.
• Keep the noise down for other guests.
• Clothing. Each tub is in a private room for your group only, so what you wear is up to you and your companions.

Getting there

Te Aroha is on State Highway 26 in the eastern Waikato, between Paeroa and Morrinsville, roughly an hour’s drive from Hamilton and about two hours from Auckland. The spas are at 5b Boundary Street, at the top of Te Aroha Domain where the town meets the bush on Mount Te Aroha. From the main street, walk up through the domain; the spa building is beside the Mōkena Geyser. The Hauraki Rail Trail passes through Te Aroha, so you can arrive by bike.

When to go

The spas are open year-round. Weekday afternoons are cheaper and easier to book. Weekends fill up quickly. Cold, damp winter days suit a hot tub best. If you plan to walk up Mount Te Aroha first, the operator advises resting, eating and drinking before you get in, because a hot soak after a big climb raises the risk of fainting.

Where to stay nearby

The spas do not offer accommodation. Te Aroha town has motels, B&Bs and a holiday park within a few minutes of the domain; the local tourism site, tearohanz.co.nz, lists them.

Safety notes

• Fainting. The operator’s health checklist warns that hot mineral water lowers blood pressure. Eat within two hours before your soak, drink plenty of water, and do not overheat the tub. If you feel dizzy, pull the emergency cord.
• Medication. If you take beta-blockers or have low blood pressure, read the checklist on the spa’s website first. The advice is to keep the temperature down and to get out slowly.
• Pregnancy. Bathing is not recommended in the first trimester. Later in pregnancy, check with your midwife or doctor, tell staff, and they will give you a thermometer to keep the water below 100°F38°C for no more than 30 minutes.
• Babies may bathe in water below 100°F38°C for up to 30 minutes, with their head kept above the water.
• Accessibility. The operator does not publish access details for the tub rooms. Call before you visit if you have limited mobility.
• The geyser discharges boiling water. Stay on the paths.

History

Māori in the area knew and used the springs long before Europeans arrived. After chief Mōkena Hou gifted the land, the government built a health resort around the springs, and in the late Victorian and Edwardian years about 30,000 visitors a year came to take the waters, according to Hamilton & Waikato Tourism. Rotorua overtook Te Aroha as the country’s leading spa town in the early 1900s, but the domain stayed in use. Several buildings survive: the Cadman Bath House is now the Te Aroha and Districts Museum, and the No. 2 Bath House is part of Swim Zone Te Aroha.

Nearby stops worth adding

Swim Zone Te Aroha, in the same domain, has a large heated pool, an outdoor spa pool and a toddler pool. The Te Aroha and Districts Museum in the Cadman Bath House tells the spa town’s story. Mount Te Aroha is the highest peak in the Kaimai Range, with walking tracks starting from the domain. For a bigger geothermal day, Rotorua’s Polynesian Spa is about an hour and a half south-east.
