A third attack on October 24, took place in the same location as the previous.

The fourth attack in Moire Park in Massey, West Auckland, occurred on October 26, at around 6.30pm, and the woman feared she would be raped when her attacker pulled her tights and underwear down.

The fifth and final attack happened while a woman was running between Browns Bay Rd and Beechwood Rd on November 8.

The teenager was remanded in custody until his next court appearance.
