What is the largest and northernmost of New Zealand's main Kermadec Islands?

Raoul Island is the largest and northernmost of New Zealand’s main Kermadec Islands.

Also called Sunday Island or Rangitāhua, Raoul is a volcanic island in the southwestern Pacific, positioned between New Zealand and Tonga. It covers about 29.38 square kilometres and rises to 516 metres at Moumoukai Peak. Its landscape is dominated by the caldera and rugged volcanic terrain of the Raoul volcano, which has produced powerful eruptions over thousands of years.

The island is often confused with nearby Macauley Island, the second-largest of the main Kermadec Islands, or with Nugent Island, which is the northernmost island in New Zealand’s territory but is only a small satellite of Raoul. Raoul is also notable for conservation work: invasive rats and cats were eradicated in the early 2000s, allowing native seabirds and red-crowned parakeets to return. The island lies within the Kermadec Islands Marine Reserve, created in 1990.
