Te Rauakaaka is a 212-hectare regional park and nature reserve on the south side of the Waimakariri River, in Brooklands, Christchurch. It includes a saltmarsh, the Styx River mouth, and freshwater wetlands that support threatened swamp birds and waders. The website says it is popular with bird watchers, families and anglers, and it has a peaceful setting with old willow trees shading spring-fed waters.
The sole vehicle entrance is off Kainga Road, on the eastern side of the railway line. The Whites Crossing Picnic Area, with four tables and public toilets, is reached by a bridge across the Ōtūkaikino Stream. Dogs must be kept under effective control. Gas barbecues are allowed if they are used in areas clear of vegetation, and fires are not allowed. A shared track runs from Whites Crossing to Brooklands Lagoon. One reviewer describes it as a great place for a quick walk, which can be muddy after rain.
