"People need to be prepared and take the warnings seriously," says Mayor Alex Walker.
"Staying up to date with the latest information is the best thing people can do.
"Things are rapidly changing, and we urge people to follow our Facebook page, website and listen to CentralFM for the latest updates."
With a boil water notice in place for Waipukurau, free potable water is available for residents at Russell Park.
Residents are encouraged to stay away from floodwaters due to potential contamination and to take notice of road closure signs, with damage likely to the road and bridge structures in rural areas unknown until floodwater recedes.
"We've already seen the loss of the Tarewa Bridge, part of the Tukituki Trails, from this weather event, and we can expect to find more damage and resulting clean-up work, particularly in our rural areas as floodwaters recede," says Mayor Walker.
"We are a strong and connected community and I encourage people to continue looking out for each other and our neighbour in the way we're known for."
