People could keep up to date with closures by checking the transport agency's website, he said.
Taranaki clean-up
A rural Taranaki school might not be opening tomorrow after it was hit by flooding.
Yesterday New Plymouth had the equivalent of a typical July's-worth of rainfall in just four hours.
Flooding swept through Rahotu, a rural town about 40 minutes south of the city. A tweet from MetService yesterday showed flood waters raging through the school, although the red level rain warning for Taranaki has now been lifted.

Rahotu School principal Brigitte Luke said they will try to assess the damage today once the water's receded and if roads can be crossed to get there.
She said one of the priorities will be ensuring the sewerage system's held up.
She said students and staff are equipped for at-home learning if that is what is required until the school can open.
MetService says New Plymouth usually averages 82mm of rain across the entire month of February.
But it said between Saturday and Sunday New Plymouth received 192.6mm of rain, while Mt Taranaki received 485mm.
An extraordinary amount of rain fell in Taranaki during the Red Warning event on Saturday and Sunday after such a dry January, and many communities were impacted.
