The most northly and western point of New Zealand is not Cape Reinga. We realised this after reading the full description in the Lonely Planet. However it is the most northerly accessible point of the North Island. Cape Reinga is the point where the Tasman Sea and the Pacific Ocean meet, with swell 10m high at certain times. At the tip of the Cape is a Light House, and the freshest air I have breathed for a long time.
It takes about 3hrs to drive from Paihai to Cape Reinga, if the trip was solely for the light house and the cape it would be a little excessive. Fortunately on the end of Ninety Mile Beach are some magnificant sand dunes. Walked through the dunes feeling like an extra from Star Wars.
Wondering if Cape Reinga is the most northerly point? - Check this map - spoiler - it ain't 😊
