The High Court and Supreme Court have sided with Emmons Developments in its case against insurers Vero and Mitsui Sumitomo, clearing the way for the developers to rebuild its Central Christchurch hotel.
Emmons will now be applying for resource consent and continue work on the building which was badly damaged in the 2011 earthquakes.
The 14-storey building was formerly a Rydges hotel, and its restoration should begin later this year.
In 2018, workers had begun stripping out damaged parts of the property, but will now be able to fix the foundations.
Singapore-owned Emmons Developments bought the property in 1990 and had completed refurbishments just before the earthquakes.
Since the earthquakes, Rydges had moved to a new Christchurch property for its hotel, and so Emmons will need a new operator.
