Rangitoto Range is in the Pureora Forest Park in the North Island of New Zealand.

It has the headwaters of the Waipā, Puniu and Mōkau Rivers and forms the eastern boundary of the King Country.

Endangered species present include North Island kōkako, kākā, falcon, North Island brown kiwi, blue duck, bats and Hochstetter's frog.

[1] The Range is formed of Late Jurassic to Early Cretaceous Manaia Hill Group greywacke (a form of sandstone, with little or no bedding, fine to medium grained, interbedded with siltstone and conglomerate, and with many quartz veins), buried in many places by Quaternary ignimbrites.

The main ignimbrite is the Ongatiti Formation, up to 150 m thick of compound, weakly to strongly welded, vitrophyric, including pumice-, andesite and rhyolite lavas from the Mangakino caldera complex.
