Gita has gone and a large high is moving in behind it to bring a mostly dry, warm, weekend. However by Sunday the westerlies will be picking up in the South Island as a new low starts to develop in the Southern Ocean.
 
This low is being partially fuelled by the remnants of what was Cyclone Kelvin.
