Strong wind warnings are also in place for parts of Canterbury and the lower North Island with up to 140km/h in parts as another cold front blast parts of central New Zealand on Wednesday morning.
Areas on heavy rain watch overnight Tuesday:
- Bay of Plenty

MetService warns heavy rain may cause streams and rivers to rise rapidly and surface flooding and slips are also possible.
Areas on strong wind watch overnight Tuesday:
- Hawke's Bay

MetService warns strong wind gusts could damage trees, powerlines and unsecured structures.
Driving may also be hazardous, especially for high-sided vehicles and motorcycles.
The warnings come after an unexpected cold blast hit the lower South Island over the weekend bringing thick snow on the Crown Range between Queenstown and Wanaka.
