The Labor Party has won the Northern Territory election, with Chief Minister Adam Giles blaming disunity in his party for an electoral "thumping".

With 54 per cent of the vote counted the ABC was predicting Labor would likely win 18 seats in the NT's 25-seat parliament and the ruling Country Liberals party (CLP) would win only three seats.

Based on those predictions there would be four independents.

Chief Minister Adam Giles, who is struggling to retain his own seat of Braitling, conceded defeat shortly before 9:00pm (ACST) on Saturday.

"About five minutes ago I had the opportunity of ringing [Labor leader] Michael Gunner and congratulating him on taking Government," Mr Giles said from a CLP event in Alice Springs.

"Tonight, no doubt, is a landslide, it's a thumping.

"I don't think anyone would describe it as anything different," Mr Giles said.

He said the poor result for the CLP was a result of disunity within the party.

"Tonight's result is a lesson in disunity is death in politics," Mr Giles said.

"It's a result of personalities before the politics.

"It's a result of looking after one's self rather than thinking about the people," he said.

The CLP was beset with infighting during its four years in power, which saw five of its 16 elected members leave the party, plunging it into minority government.

Although one of the defectors would ultimately rejoin the party, there were up to 18 reshuffles during its term of government.

Gunner claims victory

A short time later Mr Gunner took to the podium at the Waratah Club in Darwin where he was hosting an event.

"Tonight is extraordinary. Territorians have spoken," he said.

"They have rejected the chaos of the last four years and they have chosen to place their trust in Labor."

He thanked Territorians for placing their trust in Labor.

"It is a privilege to stand here today as a servant of the public and as the new Chief Minister of the NT," Mr Gunner said.

He said he would work tirelessly, truthfully and selflessly for Territorians.

"The Territory remains a land of opportunity and I am proof of that," he said.

"A boy born in Alice Springs, who grew up in public housing in Tennant Creek and now stands here as a Chief Minister of the NT."
