Manchester Street in central Christchurch is fully open again for the first time in more than two years.
The Christchurch Earthquake Recovery Authority said the street was fully opened on Saturday night as part of continuing efforts to lift restrictions in the central business district where possible.
The reduction of the cordon coincides with a new east rebuild zone, similar to the north and south zones created by the opening of Gloucester Street.
The recovery authority says once buildings within a cordon are made safe or fenced off and roads, street lights as well as footpaths are made operational further cordons can be removed.
It aims to have all cordons lifted by the end of June.
