Wellington (Te Whanganui-a-Tara or Poneke in Ma-ori) is the capital of New Zealand, the country's second largest urban area and the most populous national capital in Oceania. It is in the Wellington region at the southern tip of the North Island, near the geographical centre of the country. Wellington is New Zealand's political centre, housing Parliament and the head offices of all government ministries and departments, plus the bulk of the foreign diplomatic missions based in New Zealand. Wellington was named in honour of Arthur Wellesley, the first Duke of Wellington and victor at the Battle of Waterloo. The Duke's title comes from the town of Wellington in the English county of Somerset.
