Christchurch's new Central City Library, Tūranga, won this year's supreme Property Council award for its contribution to the post-earthquake city and its many community facilities.
"A stunning symbol of hope, unity and rebirth," said judges of the five-level 9500sq m building, opened last October, the South Island's largest library.
A Property Council spokesperson said the awards, announced at Auckland's Spark Arena, also saw Tūranga winning the civic and arts award.
The library says Tūranga "speaks of whakapapa across generations, connections to the north and out to Te Moana-nui-a-Kiwa and the wider Pacific".
The Property Council said the building's contribution was significant.
