Te Aroha Domain Historic Area, Historic reserve in Te Aroha, Matamata-Piako District, New Zealand

Te Aroha Domain Historic Area is a historic site in New Zealand centered around natural hot springs and a large parkland. The grounds feature buildings from the early 1900s, including the Cadman Bath House that now houses the museum, along with walking paths, grassy lawns, children's play areas, a restored lakelet, and a foot pool fed by the springs.

The domain was established in 1881 on 20 acres at the foot of Mount Te Aroha, and the government took control under the Thermal Springs District Act that year. The Te Aroha Hot Springs Board was set up in 1882, and seven bath houses stood five years later. A railway to Auckland opened in 1886, and on New Year's Day 1912, 7,000 visitors arrived. The Cadman Bath House closed in 1961, and the council took ownership in 1979.

The name Te Aroha means "love" in Māori. The domain's grounds were laid out by local architect Henry Crump. Brass bands and lantern festivals drew crowds here, and on New Year's Day 1912 about 7,000 visitors arrived in the town. Māori kept free access to the hot springs after the government took over the domain in 1881.

The grounds are easy to navigate with wide pathways, open lawns, and clear areas to explore. You will find public restrooms, a visitor center, picnic facilities, and activities including bowling greens and croquet courts, with main access points clearly marked throughout.

The domain's hot soda spring, Mokena Geyser, is fed by volcanic heat and is described as the only hot soda-water geyser in the Southern Hemisphere. It sits among the Edwardian bath buildings, and its water was once bottled and sold nationwide.
