A future government led by Peter O'Neill will be cautious about implementing new media laws, and will push only those that bolster press freedom.

But the PM says a changing media landscape, with the growth of internet, mobile access and social media, will see future governments passing laws to "expand and expound" on media freedoms.

Past governments had failed to create laws enabling freedom of information to support and provide clarity to PNG's constitutionally-guaranteed freedoms.

"Any future PNG government under my watch as head of government ... will be very cautious about any legislation aimed at defining or redefining the boundaries of freedom of the media, freedom of expression and freedom of information," O'Neill said in a statement.

"(Legislation considered) should only be confined to aspects of definition, responsibility and clarity of these freedoms and without any real or implied imposition of restrictive and regulatory provisions.

"There is no shortage of examples of what restrictive media and information laws have done to nation states within our region and worldwide.

The comments were delivered by Communications Secretary Kora Nua at a media freedom workshop in Port Moresby on Thursday on behalf of O'Neill.

The workshop was co-hosted by the International Federation of Journalists and the PNG Media Workers Association, and was held to launch the Press Freedom in the Pacific report. The launch in Port Moresby also coincided with World Press Freedom Day.

The O'Neill government recently caught flak from the United Nations High Commissioner for Human Rights, Navi Pillay.

Following two alleged attacks on journalists by police in recent months and the O'Neill government's recent moves to give parliament more control over judges, Pillay warned PNG was sliding towards lawlessness.

But with all signs now pointing to an election in the coming months, O'Neill's message may have also been aimed closer to home.

Parliament last week conducted a grievance debate which centred in part on the media and its coverage of the government.

Wewak MP Dr Moses Manwau told the chamber newspapers like The National were biased against the government.

"Newspapers are too biased. They must show some impartiality. What do you do with a newspaper like The National? They seem to be biased," The National quoted him as saying on Monday.

The story was printed days before Deputy Prime Minister and Logging Minister Belden Namah picked a fight with the paper's owner, timber company Rimbunan Hijau (RH), over a logging interest in the middle Ramu area.

Wong Tee Ing, a camp manager at the RH site, was threatened with deportation by Namah who said the company's subsidiary, Timber PNG, was operating illegally.

RH strongly denies this.

Citing the government's recent run in with the trade unions, National Capital District governor Powes Parkop told parliament funding should be reviewed for the national television station, Kundu 2.

"They gave (PNG Trade Union Congress general secretary John Paska) something like 10 minutes on air, and then the PM was cut off because of a technical fault," he told AAP later, referring to news coverage of the union threat to strike.

But he says attacking media freedom is not the way to go.

"I want to see them funded properly," he said.

"The last government had 20 million kina ($AUD9.4 million) budgeted for them, but they never got it. Either we fund them properly, or we privatise."
