Sandspit is a settlement in the Auckland Region of New Zealand. It is on the Mahurangi Peninsula, about 65 kilometres north of the city centre. It has experienced substantial increases in property values during the first two decades of the 21st century.

Ferries run several times a day from Sandspit to Kawau Island. Ferry service between Sandspit and Kawau first started in 1934, with a boat which was (possibly later) called Nancibel[l]. In the 1950s, Nancibel was replaced by Mairie and Kawau Isle.

Brick Bay, which is adjacent to Sandspit, has a sculpture trail along a two-kilometre path through native bush, fields and ponds.
