1815 in New Zealand

The first Christian mission is established at Rangihoua. The Hansen family, the first non-missionary family also settles there. Samuel Marsden explores the Hauraki Gulf and travels to within sight of Tauranga Harbour. The first book in Māori is published in Sydney. The first European is born in New Zealand.

Visits by sealing ships begin to decline; they are now sealing almost exclusively at the Macquarie and Campbell Islands and travel either via the east coast of New Zealand (calling at the Bay of Islands en route for refreshments) or via the southern fjords/Foveaux Strait/Stewart Island (stopping for refreshments in either/both directions).
