Norwegian media reported that some of the people in a video of Prime Minister Jens Stoltenberg posing as a taxi driver were paid for taking part.
Norway’s ruling Labour Party confirmed that 5 of 14 passengers filmed in the cab had each been paid 500 kroner ($85; 64 euros).
But while they had been asked to take part in a Labour video, they were not told what it involved, it said.
Jens Stoltenberg said he wanted to hear from real voters before polls next month.
The prime minister’s party, in power since 2005, is trailing Norway’s Conservative Party in opinion polls.

The video, made in collaboration with an advertising company in June, is due to be screened during the election campaign but has already been posted on Jens Stoltenberg’s Facebook page.
News that five of Jens Stoltenberg’s passengers were not picked up at random was revealed by Norway’s Verdens Gang (VG) tabloid.
“They’re five ordinary people who were asked if they wanted to take part in a video for the Labour Party and who knew nothing else, except that they were going to be picked up in a taxi,” party spokeswoman Pia Gulbrandsen said.
“Their spontaneity was real when they realized that the driver was the prime minister.”
None of the passengers had to pay for their ride.
Jens Stoltenberg came in for criticism for his driving, at one point jolting the car abruptly when, he said, he had mistakenly applied the brake pedal on the automatic car, thinking it was the clutch.
The two-term prime minister said he had not driven in eight years.
Norway’s Prime Minister Jens Stoltenberg spent an afternoon working incognito as a taxi driver in Oslo, he has revealed.
Jens Stoltenberg said he had wanted to hear from real Norwegian voters and that taxis were one of the few places where people shared their true views.
He wore sunglasses and an Oslo taxi driver uniform for the shift in June, only revealing his identity once he was recognized by his passengers.
Jens Stoltenberg’s exchanges with his passengers were captured on a hidden camera.
The footage – made in collaboration with an advertising company – has been posted on the prime minister’s Facebook page and made into a film which will be used as part of his campaign for re-election in September.
“It is important for me to hear what people really think,” Jens Stoltenberg told Norwegian media.
“And if there is one place people really say what they think about most things, it’s in the taxi.”

Some of the passengers who appear in the film had been told to wait for the taxi – without being told who would be driving – while others were picked up randomly and from taxi ranks.
Most of them appear to realize very quickly that there is something different about their driver, with one saying: “From this angle you really look like Stoltenberg.”
Another says she was lucky to meet him as she “wanted to send a letter”.
The conversation turns to politics in most cases.
Jens Stoltenberg engages one passenger on education, saying: “The main point is to make sure good students have something to stretch for, and to give those who struggle extra help.”
None of the passengers was charged for the ride.
Jens Stoltenberg told the VG newspaper: “I’m pretty well known in Oslo, but I tend to sit in the back seat.”

Jens Stoltenberg is popular in Norway, but opinion polls suggest he is lagging behind the opposition ahead of the election.
Asked by VG whether he would consider becoming a taxi driver full time if he lost the election, Jens Stoltenberg replied: “I thinkthe country and the Norwegian taxi passengers are best served if I’m the prime minister and not a taxi driver.”
Abhisit Vejjajiva, the former Thai prime minister, has been charged with murder over the death of a taxi driver shot by soldiers during political violence.
Abhisit Vejjajiva was prime minister when thousands of protesters took to the streets in 2010 demanding his government step down.
He gave orders allowing troops to use live ammunition on protesters, who had shut down parts of Bangkok.
Abhisit Vejjajiva denies the charge, which supporters say is politically motivated.
More than 90 people, both civilians and soldiers, were killed in the protests, which went on for over two months.
Abhisit Vejjajiva and his deputy at the time, Suthep Thaugsuban, are the first officials to face charges in connection with the deaths.
The move was announced last week, after a court ruled in September that taxi driver Phan Kamkong had been killed by troops.

Now the leader of the opposition, Abhisit Vejjajiva has defended his order for live ammunition to be used, saying government forces had “very little option” but to act when live fire was used against them.
“We tried to negotiate with the protesters, and they wouldn’t accept any of the deals that we offered them,” he said.
“It was our duty to restore order, and that’s what we were trying to do.”
Abhisit Vejjajiva said he would fight to prove he was not guilty.
Elections held after the protests, in July 2011, were won by the party led by Yingluck Shinawatra, sister of Thaksin Shinawatra, the ousted prime minister whom many of the protesters backed.
Twenty-four protest leaders are also being prosecuted on terrorism charges.
