James Cook claimed New Zealand for Britain on his arrival in 1769. The establishment of British colonies in Australia from 1788 and the boom in whaling and sealing in the Southern Ocean brought many Europeans to the vicinity of New Zealand. Whalers and sealers were often itinerant and the first real settlers were missionaries and traders in the Bay of Islands area from 1809. Early visitors to New Zealand included whalers, sealers, missionaries, mariners, and merchants, attracted to natural resources in abundance. They came from the Australian colonies, Great Britain and Ireland, Germany (forming the next biggest immigrant group after the British and Irish), France, Portugal, the Netherlands, Denmark, the United States, and Canada.
