Nikau Creek flows within the confines of Wainuiomata Regional Park, and into the Wainuiomata River.
Nikau Creek is a tributary of Wainuiomata River. The stream meanders through the next valley beyond Sunny Grove, where Skerretts Creek courses through. Situated within the boundaries of Wainuiomata Regional Park, Nikau Creek descends from an approximate elevation of 141 meters above sea level. The Nikau Track runs alongside the creek on level ground, but it later intersects with a largely abandoned trail. This path continues to trace the creek until reaching the rear of the valley floor.
