We have the Big Picture weatherwise covering the main systems impacting New Zealand, Australia and the South Island nations this week.

High pressure zones dominate NZ while low pressure moves into Australia.

This weekend NZ gets some of that wet and windy weather out of Australia. La Nina like conditions continue to develop in the tropics but it’s quite settled there for now.

We track the rainmakers, sea conditions and temperatures over the coming week – through to this Saturday.
