On the ground floor are 19 separate tenancies, occupied by hospitality operators including Cleaver & Co, Joe's Garage and Nandos.
Located immediately opposite the Christchurch Bus Exchange, on the corner of Colombo, Lichfield and Tuam Sts, Hoyts EntX has a net lettable area of 8403sq m on 4488sq m of central city land.
Cooper says EntX is likely to draw both national and international investors, given the calibre of the property.
"International and national investors are showing strong interest in Christchurch and we expect EntX to attract considerable attention.
"As well as being opposite the Bus Exchange, it also benefits from its position between the two carparking buildings on Lichfield St and its connectivity to the CBD retail and office precincts."
Calder Stewart is also selling the former temporary police station in St Asaph St.
It was built as a stop-gap until the Justice and Emergency Services Precinct was finished.
The large format single-level station, on a 1.6ha site, sits adjacent to the Metro Sports facility.
It was officially opened in 2013 as a replacement for the former city police station on Hereford St, after it was deemed unsafe.
