during the New Zealand Wars of the 1860s. A "special town district" was created in 1883, to promote Rotorua's potential as a spa destination. The town was connected to Auckland with the opening of the Rotorua Branch railway and commencement of the Rotorua Express train in 1894, resulting in the rapid growth of the town and tourism from this time forward. Rotorua was established as a borough in 1922, elected its first mayor in 1923, and declared a city in 1962 before becoming a district in 1979. Geography Climate The Rotorua region enjoys a mild temperate climate (Cfb). Rotorua is situated inland from the coast and is sheltered by high country to the south and east of the city, resulting in less wind than many other places in New Zealand. During the winter months June – August temperatures can drop below 0 °C. Frost is common in Rotorua during its winter months, with an average of 57 ground frosts annually, and 20 nights per year below 0 °C. Snowfall in Rotorua is rare and since the 1970s has only been recorded twice. On 15 August 2011 and 13 July 2017 snowflakes fell in the town centre, and during the July 2017 snowfall, snow accumulated in the nearby Mamaku ranges and in the outer reaches of the district, where snowfall occurs on average once every three years. Suburbs Inner suburbs Outer suburbs Geothermal areas Thermal activity is at the heart of much of Rotorua's tourist appeal. Geysers and bubbling mud pools, hot thermal springs and Te Wairoa ("The Buried Village") — so named after it was buried by the 1886 Mount Tarawera eruption— are within easy reach of Rotorua. In Kuirau Park, to the west end of Rotorua, hot bubbling mud pools dot the park. Visitors can soak their feet in hot pools. A common nickname for Rotorua is "Sulphur City" due to the hydrogen sulphide emissions, which gives the city a smell similar to "rotten eggs", as well as "Rotten-rua" combining its legitimate name and the rotten smell prevalent. Another common nickname is "Roto-Vegas", likening the city's own strip of road flanked by businesses and restaurants to that of Las Vegas. The especially pungent smell in the central-east 'Te Ngae' area is due to the dense sulphur deposits located next to the southern boundary of the Government Gardens, in the area known as 'Sulphur Point'.
