Given the question: Information:  - Tonga (or ; Tongan: "Puleanga Fakatui o Tonga"), officially the Kingdom of Tonga, is a Polynesian sovereign state and archipelago comprising 169 islands of which 36 are inhabited. The total surface area is about scattered over of the southern Pacific Ocean. It has a population of 103,000 people of whom 70% reside on the main island of Tongatapu.  - Wellington is the capital city and second most populous urban area of New Zealand, with residents. It is at the south-western tip of the North Island, between Cook Strait and the Rimutaka Range. Wellington is the major population centre of the southern North Island and is the administrative centre of the Wellington Region, which also includes the Kapiti Coast and Wairarapa. As the nation's capital city, the New Zealand Government and Parliament, Supreme Court and most of the civil service are based in the city.  - The South Island or Te Waipounamu ("Mori") is the larger of the two major islands of New Zealand, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers and is influenced by a temperate climate.  - New Caledonia is a special collectivity of France located in the southwest Pacific Ocean, east of Australia and east of Metropolitan France. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. Locals refer to Grande Terre as "" ("the pebble").  - New Zealand is an island nation in the southwestern Pacific Ocean. The country geographically comprises two main landmassesthat of the North Island, or Te Ika-a-Mui, and the South Island, or Te Waipounamuand numerous smaller islands. New Zealand is situated some east of Australia across the Tasman Sea and roughly south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long period of isolation, New Zealand developed a distinct biodiversity of animal, fungal and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington, while its most populous city is Auckland.  - Auckland is a city in the North Island of New Zealand. It is the most populous urban area in the country. Auckland has a population of , which constitutes percent of New Zealand's population. It is part of the wider Auckland Regionthe area governed by the Auckland Councilwhich also includes outlying rural areas and the islands of the Hauraki Gulf, resulting in a total population of . Auckland also has the largest Polynesian population of any city in the world. The Mori language name for Auckland is or , meaning "Tmaki with a hundred lovers", in reference to the desirability of its fertile land at the hub of waterways in all directions. It has also been called karana, the Mori enunciation of "Auckland".  - Fiji ((), officially the Republic of Fiji, is an island country in Melanesia in the South Pacific Ocean about northeast of New Zealand's North Island. Its closest neighbours are Vanuatu to the west, New Caledonia to the southwest, New Zealand's Kermadec Islands to the southeast, Tonga to the east, the Samoas and France's Wallis and Futuna to the northeast, and Tuvalu to the north.  - Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. Australia's capital is Canberra, and its largest urban area is Sydney.  - The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east.  - Kaikohe is a town in the Far North District of New Zealand, situated on State Highway 12 about 260 km from Auckland. It is the largest inland town and highest community above sea level in the Northland Region. With a population of just under 4000 people it is a shopping and service centre for an extensive farming district and is sometimes referred to as "the hub of the north"  - The Southern Alps (Mori: K Tiritiri o te Moana ) are a mountain range extending along much of the length of New Zealand's South Island, reaching its greatest elevations near the island's western side. The term "Southern Alps" generally refers to the entire range, although separate names are given to many of the smaller ranges that form part of it.  - The Far North District of New Zealand, as its name suggests, is the northernmost district within New Zealand, consisting of the northern tip of the North Island. The current mayor is former local Member of Parliament John Carter.  - The Northland Region (Mori: "Te Tai Tokerau", also "Te Hiku-o-te-Ika", "the Tail of the Fish" (of Maui)) is the northernmost of New Zealand's 16 local government regions. New Zealanders often call it the Far North, or, because of its mild climate, the Winterless North. The main population centre is the city of Whangarei and the largest town is Kerikeri.  - The Taupo Volcanic Zone is a highly active volcanic V shaped area in the North Island of New Zealand that is spreading east -west at the rate of about 8mm per year. It is named after Lake Taupo, the flooded caldera of the largest volcano in the zone.  - Lake Taupo is a lake situated in the North Island of New Zealand. It lies in the caldera of the Taupo Volcano. With a surface area of , it is the largest lake by surface area in New Zealand, and the second largest freshwater lake by surface area in geopolitical Oceania after Lake Murray (Papua New Guinea). Motutaiko Island lies in the south east area of the lake.  - The North Island or Te Ika-a-Mui ("Mori") is one of the two main islands of New Zealand, separated from the slightly larger but much less populous South Island by Cook Strait. The island's area is , making it the world's 14th-largest island. It has a population of   - A caldera is a large cauldron-like depression that forms following the evacuation of a magma chamber/reservoir. When large volumes of magma are erupted over a short time period, structural support for the crust above the magma chamber is lost. The ground surface then collapses downward into the partially emptied magma chamber, leaving a massive depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Only seven known caldera-forming collapses have occurred since the start of the 20th century, most recently at Bárðarbunga volcano in Iceland.  - Tectonic uplift is the portion of the total geologic uplift of the mean Earth surface that is not attributable to an isostatic response to unloading. While isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and underlying mantle, and flexural support due to the bending of rigid lithosphere.  - Cook Strait lies between the North and South Islands of New Zealand. It connects the Tasman Sea on the northwest with the South Pacific Ocean on the southeast, and runs next to the capital city, Wellington. It is wide at its narrowest point, and is considered one of the most dangerous and unpredictable waters in the world.  - The Ngawha geothermal field is a geothermal area in the North Island of New Zealand . It is situated approximately 5 km east of Kaikohe and is centred on the village of Ngawha Springs . The field covers an area of around 25 km² and as such , is much smaller than the only other geothermal field in New Zealand , the Taupo Volcanic Zone . The hot springs arising in this area are slightly acidic and are rich in ammonia , bicarbonate , boron and mercury , which is not typical of other springs in New Zealand .  - A town is a human settlement larger than a village but smaller than a city. The size definition for what constitutes a "town" varies considerably in different parts of the world.  - The Tasman Sea (Mori: "Te Tai-o-Rehua") is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand. It measures about across and about from north to south. The sea was named after the Dutch explorer Abel Janszoon Tasman, who was the first recorded European to encounter New Zealand and Tasmania. The British explorer Captain James Cook later extensively navigated the Tasman Sea in the 1770s as part of his first voyage of exploration.  - Ngawha Springs is a small settlement approximately five kilometres east of the town of Kaikohe, Northland in New Zealand.
