It also seems that most New Zealanders' ancestors migrated from Britain in the mid 19th century right up to 1920s, with significant numbers still coming later from the "10-pound Pommies" days after WWII up until Britain's accession to the EEC in 1973. By the time of the Industrial Revolution, the notion of British nation (either the state of Great Britain or the British Empire) had become the vogue and England, Scotland, and Wales became more like "internal regions" in conception.

In contrast, British migrants to America were from the Mayflower days or 17th to 18th centuries. IMHO the idea of Britain as a united country were less strong in those days.

Nice write up on the Welsh in New Zealand. I had always wondered whether the preference for singing in parts had any influence in America. It turns out the most of the village of Merthyr Tydfil joined the LDS church. When they came to America, they missed singing in parts as they headed to work in the mines. They solved that problem by forming the Mormon Tabernacle choir. The director has been Welsh from the beginning. Most of the choir members today still have Welsh roots.
