Rural road users are being urged to be on the lookout for dairy cows being moved between farms over the next few weeks.
South Wairarapa district councillor Keith Sexton, who works on a dairy farm, said farmers in his area would start moving their herds to run-offs this week as part of gypsy day.
The annual event marking the start of the new dairy season sees hundreds of stock and people movements off and on dairy farms across New Zealand.
The farm he worked on was moving its stock on Friday, he said.
Although known as gypsy day, it stretched out over two to three weeks, Mr Sexton said.
