Queenstown and Wānaka residents woke up to widespread flooding this morning, and are preparing for the lakes to rise even further.
MetService meteorologist Tahlia Crabtree said the region had been experiencing unprecedented rainfall.
"Generally for the month of December, Queenstown would only see approximately 60mls of rain. But they've had that much rain in the past week."
Crabtree said headwaters are causing the lakes to rise, and residents should continue to monitor the MetService website, where the warnings are constantly being updated.
A heavy rain warning remains in place until the weekend.
