Basement flooding in several new Christchurch buildings may be due to rainfall – so why did it disappear during lockdown? The flooding could be due to a host of factors including weather events, building infrastructure and river flows. A Christchurch City Council spokeswoman said the council had not experienced any significant flooding at any of its facilities with basements in the CBD.
