Kaiwharawhara is an urban seaside suburb of Wellington in New Zealand's North Island. It is located north of the centre of the city on the western shore of Wellington Harbour, where the Kaiwharawhara Stream reaches the sea from its headwaters in Karori. It is a largely commercial and industrial area and thus has little residential population. A recent housing development up the hillside towards Te Kainga has increased the resident population.

The Kaiwharawhara Stream is a stream in the North Island of New Zealand – it flows through the northwestern part of New Zealand's capital, Wellington. Its headwaters lie within the suburb of Karori, and it passes through other suburbs and Otari-Wilton's Bush before reaching the western shore of Wellington Harbour in Kaiwharawhara near the terminal of the Interislander Ferry. Part of its length runs roughly alongside the Johnsonville Branch railway, a branch line that once formed part of the North Island Main Trunk Railway – the latter now passes over the stream near its mouth.
