From the beginning... Pakuranga Stream starts at a storm drain on Casuarina Road. It then runs along Aviemore Drive. Soon it joins up with another stream calling it a tributary. Then it runs under Cascades Road and joins it with another stream making it officially a big stream known as a river. Then it runs under Ti Rikau Drive. Eventually the river joins with another river and soon enough it leads to Half Moon Bay.
