Acting District Commander Superintendent Sue Schwalger said extra cops would be on the streets to deter any would-be criminals from taking advantage of "the current situation".
"Anyone coming into the CBD this evening is asked to stay away from the cordoned off areas which are there for good safety reasons.
"We want people to feel safe in the city and be reassured by the police presence."

Wellington City Council spokesman Richard MacLean all council buildings including the library, the City Art Gallery, and council offices were closed this morning.
An Insurance Council spokesman said it was too early this morning to put a cost on the quake.

Willis St's Mercure Hotel, which had thought to have sunk by about 5cm in one corner, had now been taken off the danger list.

Fifteen square metres of sea wall and road had slumped into the sea at the southern end of the container terminal, Wellington harbourmaster Captain Mike Pryce said.
Two rafts used at Oriental Bay during the summer that were being stored on dry land had ended up back in the sea, he said.
Also taking an unscheduled dip was a six-tonne buoy – one of two used at Barrett Reef – which was being stored by the seawall.
Captain Pryce said the slumping should not affect CentrePort operations.
‘‘But they might have to re-route trucks leaving the port. The damage is quite severe and what is left is pretty precarious.’’
A pilot boat was this morning taking depth soundings of Wellington Harbour to check if the sea floor had shifted as a result of the quake.
‘‘We don’t expect that it has, but we want to see.’’
Victoria University geophysics professor Euan Smith said as we moved further away from the 6.5 magnitude quake at 5.09pm yesterday the aftershocks were ‘‘decaying’’.
It meant the quoted chance of another big quake, of magnitude 6 or over, was about 30 per cent last night.
It was now down to about 10 per cent.
But there was uncertainty about which exact fault caused the quake, which was a different ‘‘faulting style’’ to those yesterday morning and Friday morning.
The earlier quakes were caused by tectonic plates slipping under and over one another.
But last night’s was the sideways movement of two plates.
‘‘It’s an ambiguity we can’t resolve... given the uncertainty in faulting styles has changed it’s even more unpredictable than it was.
‘‘We now have two things happening at once.’’
It was still possible to have another quake that was ‘‘strong and dangerous’’.
The sideways-movement quakes were less likely to cause a tsunami, though they had potential to cause an underwater landslide which could trigger one that could endanger Cook Strait-edge site.

The quake was bigger than Christchurch's devastating February 22 shake - and released energy equivalent to 100 "Hiroshima" nuclear bombs.
GNS Science seismologist Stephen Bannister said Wellingtonians could count their blessings it wasn't centred closer to the capital.
"If it had been under the city we would have been looking at equal damage or close to what happened in Christchurch."
In the capital, thousands of people huddled under tables and door frames, as the shuddering brought masonry and shattered glass showering down on to the street.
The fire service had more than 60 callouts last night and had to rescue three groups of people stuck in apartment block lifts when the quake struck.
In Brandon St, about 20 people were evacuated from Brandon Village accommodation after a large concrete slab was shaken loose.
Part of Civic Square under the overbridge was also cordoned off after pipes on the fourth storey of Wellington Library burst, sending water gushing on to the footpath below.
