MetService have issued a rare Red Warning for Buller as heavy rain continues to lash parts of the South Island.
The wild weather is expected to bring heavy rain and northerly gales for many parts of central and northern New Zealand.
An active front over the Tasman Sea moves slowly eastwards across central and northern New Zealand today, followed by a broad trough on Sunday. This front has brought heavy rain to many parts of central New Zealand and is expected to bring further heavy rain and northerly gales to central and northern areas.
A red warning remains in force for heavy rain in Buller. Further flooding is quite likely in some areas, as are slips and disruption to transport, and power outages. Some communities could become isolated.
Also, severe northerly gales about parts of central New Zealand could damage trees, powerlines and unsecured structures, and make driving hazardous.
People are advised to stay up to date with the latest forecasts in case any changes are made, or further areas are added.
