In ancient times, the daughter of a high born chief was bathing in its crystal waters and wore a tiki (sacred greenstone neck ornament). The piece dislodged itself while she swam and the blue waters of the lake are believed to still be hiding the tiki tapu. Lake Tikitapu sits alongside Lake Rotokakahi (Green Lake). It is a popular location for family outings and summer lake events. There is also an easy walking track around the lake.
