Unregistered raw milk suppliers around the country have been banned from selling their product.
This is the message from the Ministry for Primary Industries.
"It has been a summer of action for MPI biosecurity staff who have faced record numbers of arriving passengers," says Steve Gilbert, MPI border clearance services director.
"Despite the huge numbers, we've kept processing times down for passengers. And most importantly, our compliance statistics show we are blocking the things that pose biosecurity risk to New Zealand.
"More than 99% of passengers that went through our border checks arrived in New Zealand without any risk goods."
He says there were 14 interceptions of organic material containing fruit fly.
"Stopping fruit fly from entering New Zealand is a big focus for us. So it is good to know that we have prevented at least 14 incursions of this destructive pest this summer."
Last year MPI introduced 90 new frontline officers and 24 new detector dog teams to strengthen biosecurity at the border.
"We have also upped our risk assessment levels, invested heavily in building awareness about New Zealand's biosecurity rules and introduced a mobile x-ray scanner to help clear cruise ship passengers.
"To ensure the biosecurity message gets through, officers have been taking a stricter approach with fining passengers who break the rules. This can be seen in the number of infringement notices this summer. We issued 2288 fines, a rise of 41 percent from last year.
"The new measures have made it harder for air and cruise passengers to accidentally or deliberately carry risk goods into New Zealand."
