A woman was indecently assaulted on Mt Wellington by a man who followed her and urinated in front of her.
Police are appealing for witnesses to come forward after the woman was attacked on Sunday, July 3.
Between 9.30am and 10am the woman walked up to the Mt Wellington summit.
As she made her way back down the mountain, a man who is believed to have parked his light coloured van at the top, followed her.
He then urinated in front of the woman and then grabbed her, indecently assaulting her. She managed to fight him off and he fled.
Police believe he ran back to his van at the summit and then drove away.
A member of the public saw the woman was upset and called police.
Officers searched the area but the man was not found.
Detective Keri Kimpton said police needed to speak to anyone who was in the area at the time.
"Mt Wellington is a reasonably busy place on a Sunday morning, lots of people walk and run up there at that time and often take selfies or photos at the top.
"We'd like to hear from anyone who was there around the time that this occurred, particularly anyone who took photos, to get in touch with us please."
Kimpton did not believe the incident was linked to the ongoing investigation of indecent assaults against women in Onehunga.
"Any incident like this is alarming and we are obviously very keen to catch this person," Kimpton said.
"We'd also like to hear from anyone who has seen someone of that description behaving suspiciously at another time on Mt Wellington."
The offender is described as the following;
• Aged 25-30 years old.
• Maori or Pacific Islander.
• Was wearing shorts.
• About 170-172 cm tall.
• Dark/black curly hair, about collar length.
• Slight moustache and stubble on cheeks.
Anyone with information is asked to contact Detective Keri Kimpton on 09 524 1921.
