The Northern Territory government has announced a six day extension to the youth curfew in Mparntwe/Alice Springs originally slated to end on Wednesday morning, calling it a "common sense" approach.

The new curfew expiry on Tuesday April 16 will take in the entirety of the school holidays, which traditionally sees more young people from outside of Mparntwe/Alice Springs come into the embattled town.

On Tuesday, Chief Minister Eva Lawler announced the extension, telling reporters the anecdotal response from Mparntwe/Alice Springs' residents surrounding the curfew was positive, noting some had told her it was the "best thing that has happened" to the town.

"It really was a circuit breaker," Ms Lawler said. "People are feeling so much safer and more comfortable."

"Also the data that police have around the numbers [of kids on the street outside curfew], it started at 60 and dropped down to 40, it went up a little bit over the weekend. It is great to see those numbers have been reduced — 30 kids on average.

"Maybe there is a small group continuously on the street, but we are putting services around that...to me the curfew has been a great success."

She said her government had heard from about 45 people in the Mparntwe/Alice Springs on Monday, admitting they "did not consult widely" when the initial curfew announcement was made.

"The overarching [theme] was that we need to keep the curfew in place, particularly over the school holidays," Ms Lawler said, noting it will end on Tuesday next week as Monday is a pupil free day.

Discussions of an extension were formally flagged to the media on Monday, when NT Police Commissioner Michael Murphy said the Territory Emergency Management Council (TEMC) would meet in the afternoon to discuss extending what he described as a "really effective" curfew.

Ms Lawler said the government had taken the advice from the TEMC on extending the curfew.

"We'll continue to monitor the curfew like they have over the last 10 days or so they'll continue to monitor it to 6am on Tuesday morning," she said.

The opposition CLP released a statement on Tuesday calling for the curfew to be extended to the end of April in order for enough data to be gathered to judge the effectiveness of the measures.

It was initiated by the NT government as a result of violent incidents on March 26 in the town, after tensions surrounding the death of 18-year-old eastern Arrernte man Kumanjayi Petrick in a car accident erupted.

The violence saw dozens of people attacking a local tavern, before police reported an estimated 150 people in the Hidden Valley community outside of the city, "going armed in public and engaging in violent conduct".

Federal Minister for Indigenous Australians, Linda Burney, and the Central Australian Aboriginal Congress have called it a necessary "circuit breaker" for the town, but it has been criticised by leading groups Amnesty International Australia, NATSILS and NAAJA as "knee-jerk" response unlikely to help the long-term issue of youth crime in central Australia.

Labor MP Marion Scrymgour, whose electorate of Lingiari takes Mparntwe/Alice Springs, told Sky News on Tuesday the curfew is a "great circuit breaker" and has allowed for calm in the town.

"Everyone wants this to work. I think the curfew was a great circuit breaker, it just put the calm in place that needed to be put in place," she said.

It's believed the curfew, which bans young people under the age of 18 from entering the Mparntwe/Alice Springs CBD from 6pm to 6am without a valid reason, has been widely supported in the community, and has brought a level of calm, with the number of "interactions" with police having dropped since the curfew was introduced.

As of Monday, there had been no arrests for curfew breaches.

A "valid reason" for anyone under to be out during curfew can include working as part of their employment; accessing a youth-related service; being with a responsible adult; and having a medical emergency.
