TVNZ says it has had no approach from SkyCity to buy its land for the proposed convention centre, contrary to the Prime Minister's assurances to Parliament yesterday.
The state broadcaster also ruled out any commercial arrangement with the casino company.
TVNZ's position is in contrast to statements by John Key to Parliament yesterday when he was quizzed over what discussions he and his staff had with SkyCity about TVNZ's taxpayer-owned land.
Mr Key told Parliament the casino had worked out it needed more land. The larger design came after Mr Key's instruction to "think outside the box" resulted in a design for much larger convention centre.
Mr Key said he was aware "if Skycity was to build a larger convention centre than the original one they wanted, at some point I was aware that they would need to acquire land".
He said: "It is pretty straightforward. SkyCity, after it decided it would be prepared to enter an expression of interest process to have a larger convention centre, went off to its architects.
Its architects designed such a thing, realised they needed more land, worked out who owned the land, and approached Television New Zealand."
Mr Key was quizzed over how an approach could be made without the TVNZ board being aware of it. He responded: "I cannot speak for the Television New Zealand board, but I am finding it reasonably hard to believe that Television New Zealand entered a commercial agreement with Skycity to sell land that it owned, and it did so without its board knowing."
TVNZ spokeswoman Megan Richards told the Herald on a number of occasions last year there had been no approach by SkyCity for the land and no deal had been done.
Today, she said the position had not changed. "We have had no approach from SkyCity. We have no commercial arrangement with SkyCity. If we were to be approached by SkyCity we would have to consider it on its merits."
She said there were portions of land which TVNZ might consider it could sell and others which it would not. She said SkyCity had historically expressed an interest but not in recent years and never in relation to the proposed International Convention Centre.
Mr Key was questioned by NZ First leader Winston Peters, who accused him of a "secret side-deal in favour of his mates at the casino".
Mr Peters said TVNZ's board had heard nothing of land being sold and asked if Mr Key had promised the casino he would "privatise TVNZ's assets" as part of the deal.
Mr Key responded by saying a lack of knowledge might show "board process needs to be improved, and maybe the mixed-ownership model would work for it".
He added there were no plans to sell TVNZ or change its structure.
The casino's desire for land emerged in the Auditor-General's report into the proposed deal. In August 2010, then-economic development minister Gerry Brownlee asked the casino if it was able to get more land for a bigger convention centre.
The report linked the bigger design to the Gambling Act changes the casino wanted, stating: "SkyCity recalls the Minister indicating at the meeting that the Government's willingness to consider regulatory reform depended on SkyCity meeting the requirements of a bigger convention centre on a larger site."
In September 2010, the casino produced a design showing more land was needed, telling the Government it wanted it to buy the land for the project.
