Niue is the world's smallest independent nation. It sits in among Tonga, Samoa, and the Cook Islands in the South Pacific Ocean. It has strong ties with New Zealand, which conducts many diplomatic relations on its behalf. In her capacity as Queen of New Zealand, Queen Elizabeth II is Niue's head of state.
However, these strong ties have seen many residents leave the island. Niue had a population of around 5,000 in the 1960s; that figure is now just over 1,500, with about 24,000 Niueans estimated to be living in New Zealand.
Interestingly in 2003, Niue became the world's first 'wi-fi nation', with everyone living on the island given access to free wireless internet.
