He said the continuous rain had saturated the bank where the slip occurred, which made it softer and looser.
"We're going to be monitoring the Wellington roads and banks, because there's lots of rain coming down so we have to monitor the sites to make sure we keep them safe."

When the Herald visited the cafe at around 10am, there had only been one customer all morning.
"A couple of people have been texting me trying to get through, but they won't go the long way because it'll take ages."

Yesterday MetService severe weather forecaster Mads Naeraa-Spiers told the Herald there was lots of unstable land in Wellington, being hilly.
"It's been raining pretty much since Monday, so the ground is soggy and there will be slips."
MetService has now lifted the heavy rain warning that was in place yesterday, but it's still looking like a wet weekend ahead for Capital residents.
