Waiwera is a small town in the north of the Auckland Region in New Zealand.^[3] Waiwera is 6 km north of Orewa, 6 km south-east of Puhoi, 23 km south-east of Warkworth and approximately 35 km from the Auckland City centre. The settlement lies at the outlet of a river also called Waiwera. Less than 1 kilometre north of the Waiwera turn-off lies the turn-off to Wenderholm Regional Park which is situated on the far side of the headland to the north of the Waiwera River outlet.

The name is of Māori origin and means "Hot Water" (Wai = Water and Wera = Hot),^[4] and is a shortened version of the traditional name Waiwerawera.^[5]

Its main claim to fame was the hot water springs which were well known in pre-European times and reputedly visited by Māori from as far away as Thames. The first European settler to promote the springs was Robert Graham who established a health resort in 1848. During the late 19th century there was a regular steam ferry service from Auckland.^[6] The commercial hot pools closed in 2018.^[7]
