The government has also undertaken to compensate SkyCity if the terms of the concessions are changed during the life of the agreement and also compensate the company if the casino duty or other casino-related taxes is increased from signing until four years after the centre is opened.
"It all seems very close to what I was expecting," said Jeremy Simpson, an analyst at Forsyth Barr, who has a 'buy' rating on SkyCity. Simpson had already factored today's deal into his rating of the company, which is trading at "a significant discount" to his target price of $5.13.
A Reuters survey of eight analysts has a consensus rating of 'outperform.'
The agreement signed this morning between the government and the company is the culmination of almost four years of talks in what was a controversial decision to award the tender to SkyCity, the only interested party to propose meeting building costs for the centre.
"This will make us more competitive on the international stage," SkyCity's Morrison told reporters at the briefing. It will allow the company to provide the facilities and services "that our interstate and international guests expect."
The total cost of the development includes land costs of $87 million. Much of the land is currently owned by state-owned Television New Zealand, which said today it had not yet been approached about the deal and would consider any offer on its merits.
Labour Party leader David Shearer criticised the deal as a "jackpot" for SkyCity which binds future governments to compensating the company for any future changes in either the concessions or levies.
Today's binding heads of agreement now needs to be followed by legislation and local council approvals.
Economic Development Minister Steven Joyce said the convention centre will add an estimated $90 million a year to the local economy, create 1,000 jobs during construction and 800 jobs once the centre is running. It is estimated the centre will draw some 33,000 additional conference delegates to New Zealand each year.
Construction is scheduled to start in 2014 with the centre completed in 2017.
