Demolition of most of Christchurch's QEII Park Recreation and Sport complex will begin this month and is expected to take about 18 weeks.
A statement from the city council said a contractor would be on site this week, fencing would be erected, items removed and then the demolition would begin.
This preliminary process is expected to take two to three weeks.
In April Christchurch City Council received a Notice of Demolition under Section 38(4) of the CER Act from the Canterbury Earthquake Recovery Authority (Cera).
Mainzeal Property and Construction Limited was awarded the contract for demolition.
