. In 1986–1987, the building was refurbished, had its parapet removed and was reclad in steel.

Structural design

Manchester Courts is believed to have been the first steel reinforced commercial building in Christchurch. The foundations and the two lower stories were made from reinforced concrete. The upper five stories had external unreinforced brick columns that were load bearing, while the interior was made of steel framing.

Demolition

Manchester Courts suffered significant structural damage in the 2010 Canterbury earthquake

 (4 September). The masonry columns were left badly cracked on level three and four and showed shear failure. According to the New Zealand Society for Earthquake Engineering, this was due to the load transfer from the reinforced concrete floor to the unreinforced brick columns, and was further caused by the two storey building adjoining on the south side stopping to provide lateral support at that height. Diagonal cracking on the top floor indicated damage from torsional forces.

The building was deemed unsafe and was one of just two historic CBD buildings the City Council initially proposed for immediate demolition. That decision was reversed hours later when the building's owner proposed to dismantle the building over several weeks. A 60 m (196.9 ft) cordon was established around the building to guarantee public safety.

 voted 10 to 2 at their 6 October 2010 meeting that the building was a safety hazard and should thus be demolished. The council's CEO was given powers to issue a demolition warrant, which avoided the usual resource consent process that could take up to 18 months. The demolition warrant could be granted under section 129 of the Building Act 2004, where "immediate danger to the safety of people is likely". Consequently, resource consent was not required for the demolition.
Heritage enthusiasts and others protested against demolition, arguing that the masonry columns would have been reinforced with steel, and that the council should obtain its own engineering report, not rely on that commissioned by the building's owner. The owner presented evidence of further damage in aftershocks and pressed for urgent demolition, saying he had been advised that the building was showing signs of impending failure.

The fate of Manchester Courts attracted significant media attention. TV One had the demolition decision as their anchor story for their 6 pm news. Demolition started on 19 October, and was nearing completion in January 2011. The building, significantly weakened by the removal of key structural supports by demolition engineers, withstood a number of large aftershocks without collapsing.

During the demolition, an opponent of the demolition said he had photographs showing that the building did indeed contain substantial steel reinforcement. The building's owner said that less steel had been found than expected, and the mayor stood by the decision to demolish.
