SkyCity Entertainment Group may not stand to gain as much financially as projected from the NZ International Convention Centre deal.
Chris Gaskin of Devon Funds Management questioned whether Morningstar's predictions of a $200 million value uplift was too bullish.
Gaskin backed a more measured reaction to the deal from First NZ Capital research analyst Rob Bode, who estimated only 3c to 5c would be added to the company's share price valuation - well below Morningstar's 35c.
"This is another smart deal by the Government, similar to ultra-fast broadband, where New Zealand gets a world-class infrastructure asset without having to put in a lot of money upfront, and creates much-needed jobs in the commercial construction market in addition to ongoing jobs in the tourism sector.
