A missing police dog spent its fourth night in the bush as rainy weather thwarted search efforts.
Police dog Thames went missing on Sunday during a police exercise west of Carterton in the Wairarapa.
A police spokeswoman said bad weather stopped police and volunteers from searching for the dog today.
"It was important to bring them out ahead of the rough weather. We'll be re-assessing things tonight."
She said police appreciated the help and messages of support received from the public since Thames went missing.
