Paeroa is a town in the Hauraki District of the Waikato Region in the North Island of New Zealand. Located at the base of the Coromandel Peninsula, it is close to the junction of the Waihou River and Ohinemuri River, and is approximately 20 kilometres (12.4 miles) south of the Firth of Thames. New Zealanders know the town for its mineral springs, which in the past provided the water used in a local soft drink, "Lemon & Paeroa".
