One was taken into police custody not long after and, by 1:50pm, the female police negotiator had moved next to the girl, who moved off the roof safely with her shortly after 2pm.

Bryce Street in the Barton Street block has been closed since around midday. At 1.35pm, a part of Victoria Street was also blocked off.

At least three police cars, ambulances and two fire engines were in attendance at the height of the drama.

Earlier, Northern Fire Communications shift manager Colin Underdown said someone phoned to report two young women on the roof of the shopping mall.

Fire services liaised with police to coax the second of the pair off the roof from the Bryce Street side of the building.

Centre Place manager Maureen Pearce said the shopping centre and car park remained open to shoppers, but the Bryce Street entrance was cordoned off.

DOMINICO ZAPATA/FAIRFAX NZ Police were moving closer and talking to the remaining girl at 1.50pm. The drama began about midday.

She would not comment on any potential ways of gaining entry to the roof space.

"That will be the subject of an investigation by the police and our security."

More information would be available later, she said.
