Emergency Management Otago has urged those in the region to stay put until Sunday.
Group controller for Emergency Management Otago Matt Alley said many major routes were affected by surface flooding, slips and debris.
"As we head towards nightfall, driving is only going to get trickier in much of Otago," he said.
"Staying where you are for tonight is a better option than being stranded in your vehicle or needing to be rescued from a dangerous situation."
Rain and slips have forced the closure of several key South Island roads, with more torrential rain forecast in parts of the country.
In Otago, State Highway 1 between Maheno to Reidston, SH6 between Queenstown and Kingston, SH87 Kyeburn to Outram, and SH83 between Otematata to Aviemore are closed.
An Auckland holidaymaker travelling from Omakau to Naseby in Central Otago captured a video of vehicles creeping through heavy floodwaters.
"There was lots of flooding over the roads, we went through four bits like that. It's still raining really heavily, with thunderstorms. It's rained all night," said NZME's Allison Whitney.
"We were supposed to be camping at the Naseby holiday camp but our friends have arranged some cabins for us instead so we don't have to pitch tents in this weather. It's pretty crazy weather for central Otago. You don't often see rain like this."
It's a similar story for other Central Otago campers, with tents at the nearby Ranfurly Holiday Park sitting in pools of floodwater.

Boaties using Lake Aviemore in the South Island have been warned about submerged large logs and debris that have been dislodged by the downpour.
Environment Canterbury deputy harbourmaster Gary Manch said after heavy rainfall in the Canterbury high country, the debris has ended up in Lake Aviemore, causing a potentially dangerous situation for any unaware boaties.
"The logs and debris can sit just a few inches underneath the water's surface and would cause considerable damage to any vessel that comes into contact with it."
