For some reason I have always imagined Hunua as being a great distance from Auckland, so it was with some surprise that I glanced at a map last week and learned that it is just down the motorway. A voyage of discovery ensured.
The Hunua Falls themselves are very nice, and only 100m away from the car park, but the park itself is quite large and the tracks are well maintained.
We ended up doing a 3 hour loop (Massey/Cossey) that climbed up through native bush to one of the four reservoirs in the Hunua Ranges that supply most of Auckland’s water. The track itself is nothing too special, with only one or two good lookouts, but it is pleasant enough. Being a water supply dam, Cossey’s Reservoir is only viewable from a distance which is probably just as well. I don’t want to know what I am drinking.
