Recent finds of myrtle rust and the pest plant velvetleaf in the Waikato region underline why it's crucial for farmers to take precautions as they move stock and equipment at this time of year.
Moving Day involves the mass transporting of cows and machinery around the country's roads as farm contractors relocate themselves and their stock in time for the new season.
"Biosecurity starts at the farm gate," says Waikato Regional Council's pest plants team leader Darion Embling.
"It's clear that farmers and contractors have an important role to play in preventing the spread of pest plants through good on farm biosecurity practices."
He said machinery hygiene is especially important with Moving Day coming up and the movement of stock, machines and vehicles between farms at this time.
