Darwin's satellite city of Palmerston has been hit by a massive spike in commercial break-ins and a 53 per cent rise in house robberies in the past year, new data shows.

The surge is revealed in new NT crime statistics from the Attorney-General's department.

Commercial property break-ins in Palmerston were up 70 per cent in the past year from August 2014 to the end of July this year, compared to the same period in the previous year.

According to the data, 153 commercial premises were broken into in that period.

The situation was not much better for house break-ins in Palmerston, which were up more than 50 per cent.

Sexual assaults in Palmerston were down 32 per cent, and alcohol-related assaults down 18 per cent.

Darwin painted a slightly different picture, with commercial property break-ins down 12 per cent, and house break-ins up 20 per cent.

Property damage was up more than 4 per cent, with more than 2,300 offences.

Motor vehicle theft in the Top End's capital jumped almost 25 per cent in the past year, and house break-ins were up 19 per cent.

The statistics showed assaults were up, but alcohol-related assaults were down by around 1 per cent.

When similar data was released earlier this year, Nathan Barrett, MLA for the electorate of Blain which covers Palmerston, proposed new powers to crack down on young people known to police who were out on the streets at night.

The proposed laws were criticised by justice agencies and have so far not been put before NT Parliament.

He said he was "not surprised" by the new statistics.

"The spate of property crime around Christmas time in Palmerston is captured in that data," he said.

"We've been aware for some time that there's been issues in this space and we've been working since before Christmas to find solutions to this."
