More than a quarter of the region's intensive farming operations which were required to lodge resource consent by the beginning of this year have not done so.
They now have another seven weeks to apply.
Horizons Regional Council has written to the operators - mainly around coastal Rangitikei - and is giving them until November 1 to lodge consent.
Of the 209 farms Horizons say needed to have lodged consent by January 1 this year, 131 have had consents granted and 21 are "in the process".
A further 38 applications are yet to be lodged but are "with consultants" and 19 remain "outstanding".
