[1] Council staff initially recommended demolition of all but the main auditorium, but at a meeting in November 2012, councillors voted to rebuild the entire hall.

[4] The architect Cecil Wood followed up in writing with the then-mayor, Henry Thacker, suggesting that the site under consideration should be extended to the north by closing Kilmore Street.

[10] This innovative feature formed the basis for modern concert hall design across the world; Marshall went on to advise on the Philharmonie de Paris and the Guangzhou Opera House.

[12] The Town Hall has several rooms that complemented the Christchurch Convention Centre, but the venue on the opposite side of Kilmore Street was demolished in March / April 2012.

The Rieger pipe organ is also in the Christchurch Town Hall of the Performing Arts Auditorium and the curator is international concert organist Martin Setchell.

[12] On the ground floor of the complex was previously The Boaters Restaurant, which is run by the Ara Institute of Canterbury as a training venue for the hospitality industry.

[12] The Town Hall was closed as a result of significant damage caused by the February 2011 Christchurch earthquake from liquefaction and the related lateral spreading of the ground towards the Avon River.

The project also added improvements to the town hall's design – for instance, the James Hay theatre, main auditorium, and restaurant was modified to fix issues present in the original layout.

[20] On 4 September 2020, the town hall was designated a Category I Historic Place by Heritage New Zealand, reflecting the building's "outstanding international and national significance".
