After last week's damaging cyclone, New Zealand needs to rebuild with more resilient infrastructure to cope with more frequent and intense weather events, the prime minister says.
Prime Minister Chris Hipkins has described Cyclone Gabrielle, which caused widespread damage on New Zealand's North Island and claimed 11 lives, as the country's most damaging natural disaster in at least a generation.
The cyclone followed another storm two weeks earlier that swamped New Zealand's largest city, Auckland, and killed four people.
Mr Hipkins said there had been a nine-fold increase in government spending in the 2021-22 fiscal year on helping farmers cope with floods, storms and drought.
The number of weather events that require emergency road work more than doubled from an average of 67 a year between 2018 and 2021 to 140 a year, Mr Hipkins said.
"We know that how we recover has to be done a little bit differently this time," Mr Hipkins told parliament.
"We've got to build back better, we've got to build back safer and we've got to build back smarter."
He added that New Zealand was "without question" experiencing the effects of climate change and extreme weather events were becoming more common and more intense.
"Business as usual won't work any more," Mr Hipkins said.
"We have to accept that billions of dollars of additional investment is going to be required not just to fix up what has been damaged, but to build more resilience so that we can better cope with these types of events in the future," he said.
The government is making road repair a focus of the recovery effort.
Around 250 state highways and local roads remained closed on Monday afternoon and crews were repairing 400 kilometres of highway, Mr Hipkins said.
