Dunedin ( ;
) is the second-largest city in the
South Island of
New Zealand, and the principal city of the
Otago Region. While
Tauranga,
Napier-Hastings and
Hamilton have eclipsed the city in size of population in recent years to make it only the seventh-largest city in New Zealand, Dunedin is still considered one of the four main cities of New Zealand for historic, cultural and geographic reasons.
