"The chief minister and Labor should now make a similar commitment to end their scaremongering campaign which is based on lies and deception," the party said in a statement.
After initially threatening to go to the Federation of Australian Commercial Television Stations about the advertisement, ALP national secretary George Wright told AAP there was now no need.
"We were advised by our colleagues in the Northern Territory that it had been pulled and therefore the letter wasn't necessary," Mr Wright said.
"It was completely juvenile and ridiculous and abusive," he said.
There has been no explanation so far of how the message ended up in the advertisement just days out from the election.
The NT Electoral Commission was made aware of the advertisement but will not take action.
The Australian Communications and Media Authority, the broadcasting watchdog, said it had received no complaints about the advertisement.
