TB movement controls will be relaxed on Saturday for more than 5000 cattle and deer farmers in the central and lower North Island and the top of the South Island too.
TB Free New Zealand says the relaxation of the rules in these areas reflects the progress made in eradicating the disease - through thorough regular testing and wild animal control.
Cattle and deer farmers in these areas will no longer have to test their herds before livestock leaves the property - which will mean less work and greater flexibility in selling stock.
The frequency of TB testing will also be reduced, with some farmers moving from annual testing to testing every other year.
Others will move to testing every three years.
