Oakley Creek (Māori name Te Auaunga) is a creek in Auckland, New Zealand. While heavily human-modified (being surrounded for most of its length by suburban development, especially in the upper reaches), it has a number of important ecological features, such as having the former Auckland City's only natural waterfall (which is also the largest in urban Auckland).
The least modified regions, with mostly natural channels and significant riparian vegetation, exists between approximately Blockhouse Bay Road and the inlet at the northern edge of Waterview. A walkway runs along a good part of the creek in the section northwest of Mt Albert. This area of the creek is also significant for a relatively large number of archeologically significant sites, due to the use of the creek by Maori reaching inland from the inlet (landing sites and settlement remnants), and due to the later lack of strong European settlement along this part of the area.
The creek has also inspired a local community group, "Friends of Oakley Creek" which is working to restore it to a more natural state, and improve the water quality. One of the group's major concerns is the impact of the SH20 Waterview Connection on the stream, i.e. the form this motorway is to take under or near the creek. Other concerns include the high levels of metals in the stream, such as zinc, copper and lead, from its urbanised catchment, and the fact that the culvert under Great North Road impedes fish migration.
As one of the results of community interest in the revitalisation of the stream, a set of Oakley Creek Rehabilitation Guidelines was developed for the works that will occur near or at the stream during the Waterview motorway project. These primarily include removing the currently rock-lined, tight channelisation of the stream, and reintroducing a riparian margin. Auckland Council has since adapted the NZTA/Boffa Miskell-developed guidelines for some areas of the stream not affected by the motorway.
