The Rugby World Cup Minister expects to get a report on Thursday about the future of AMI Stadium in Christchurch.
Murray McCully says the stadium suffered damage in last month's earthquake but it is a matter of determining whether that damage is cosmetic or structural.
He says the report might simply lead the government to get more reports on whether the ground will be able to host Rugby World Cup games later this year.
"Engineers have to be given time to do their work in a thorough and professional manner and we're deterined to do that. Obviously, anything we conclude ourselves needs to be concinving in the eyes of the IRB (International Rugby Board) and other relevant groups so it has to be of high quality and done to proper standards."
Christchurch is due to host seven RWC games, including two quarterfinals and pool matches involving England and Australia.
