NZ has another deep low moving in this week bringing a burst of wind and rain then colder air.

It will drive in some big waves on the western side of both islands too with dangerous marine conditions for a time late this week.

The set up means the North Island and western South Island are in for much more rain in the days ahead.

More snow for the Southern Alps and most ski fields too with a late week southerly change – but things dry back up early on Saturday for many as the low moves away.
