Christchurch earthquake rebuild authorities have shortlisted five proposals for building a new convention centre block in the central city.
The Christchurch Central Development Unit (CCDU), on Tuesday, said it had narrowed down the field for the companies vying to build the centre capable of hosting 2000 to 2500 delegates.
Twenty-two expressions of interest were lodged but only 12 met the requirements, and those were further whittled down to five.
The five were a mixture of local and overseas outfits, but CCDU spokesman Jarrod Booker would not reveal who they were or where they were from to protect their interests.
The five parties' estimated costs for building the centre were also confidential, he told NZ Newswire.
CCDU was completing a detailed business case for the convention centre and would then decide what the next step in the procurement process would be.
