Auckland Harbour Suite residents were woken up by screaming overnight as a woman was found dead after falling off an apartment balcony.
Police received reports of an "unexplained death" at the central city apartment complex on Gore St around 3:40 am.
Cordons have been put in place surrounding the area while inquiries in to the incident are still ongoing.
Brad Morrow, a student who lives on the first floor with his partner, was left in shock after peering over his balcony to find a woman laying motionless, in a pool of blood on the rooftop below.
The woman, who according to Morrow had been seen carrying alcohol into the complex, was thought to have been partying with friends in an apartment on one of the floors above.
"My partner actually witnessed her earlier with drinks and all her friends, in quite a partying mood and everything."
He says the 30-storey high apartment building was known to be a place for people to gather and party before going in to town over the weekends.
Police said the early morning incident is not suspicious.
