As you can see with the map below heavy rain pushes northwards along the West Coast of the South Island during the day. The North Island only has a light patchy shower or two in the west, mainly about Northland and Taranaki then gradually spreading to other areas in the evening.
The front that brought heavy rain to the western South Island on Saturday now moves over the North Island on Sunday, you’ll see in the map below where the areas of heaviest rain are expected. The West Coast of the South Island continues to see rain during Sunday, perhaps even some thunderstorms. Eastern parts of the country remain mainly dry however Wairarapa and perhaps at a push Hawkes Bay / Gisborne sees some rain spreading from the west at times.
Shower activity for many regions on Monday, thunderstorms are possible at times for western regions especially the North Island’s western coastline from afternoon (mainly Auckland southwards). Southerlies start pushing northwards along the South Island’s east coast bringing rain. These southerlies reach Wellington around midnight.
