Cheyenne and Harriet lived at Parakai but had extended family in Auckland.
Police are still investigating Sunday's crash, but said it was likely Harriet Hemana was not speeding. Rather, she was travelling at or under the 50km/h limit. However, police suspect neither she nor her three passengers were wearing seatbelts. The passengers suffered moderate to serious injuries and had to be cut free from the wreckage. The sole occupant of the car she hit was not injured.
The cause of the crash is still under investigation. Bottles of alcohol were found inside the vehicle, but police have still to ascertain whether alcohol or drugs were a factor in the crash.
A funeral was held for Harriet Hemana on Wednesday at her parents' Otara home before she was buried at Kaukapakapa, near her cousins.
Tributes flowed for both young women yesterday.
"Lost without the both of you Cheyenne Maraea Hemana and Harriet Hemana," a cousin of both wrote on Facebook.
