The Northern Territory has lifted coronavirus restrictions on some people coming from Sydney.

The Northern Territory has reduced the areas in Sydney covered by its coronavirus hotspot declaration.

The order covering Greater Metropolitan Sydney has been revoked but restrictions remain for people travelling from a number of suburbs.

They include Blacktown, Canada Bay, Canterbury-Bankstown, Fairfield, Parramatta, Cumberland, Burwood, Strathfield and the Inner West Council Area.

Anyone travelling to the NT from anywhere in Sydney other than those locations will no longer be required to quarantine and people currently in quarantine will be released.

"I have been closely monitoring the recent clusters of COVID-19 cases in Sydney and I am satisfied with the extensive public health response NSW is undertaking," NT Chief Health Officer Hugh Heggie said.

"I am confident in revoking Greater Metropolitan Sydney as a hotspot and declaring hotspots across the local government areas of risk to create a ring of safety.

"This is a localised and specific approach that has been reviewed and considered and provides a proportionate response."

The NT's decision follows NSW reporting five new locally-acquired virus cases on Tuesday.

Chief Minister Michael Gunner has also Territorians to increase the rate of check-ins at local venues to make contact tracing of any coronavirus cases easier.

"Six weeks ago we launched the Territory's check-in app and in those six weeks we've had over 770,000 people check-in at over 2600 venues," he said.

"But I want to make sure Territorians don't drop off the pace. If anything we've got to up our rating.

"We've got to make sure we are not complacent. It is critical we never give coronavirus a head start."

Mr Gunner said QR codes and contact tracing were essential to make sure any virus lockdowns were as short as possible.
