It is going to bring rain into places that didn't really get it last week... Bay of Plenty, Gisborne, Hawkes bay, all those areas are going to be stuck with this low for the next few days. It is going to be cold with rain."

Mr Duncan also reported that snow had already closed the Desert Rd in the central North Island with snow to 700m coupled with the white-out conditions.
