There had been the addition of policy 12A - improved physiographic zone information - which meant if landholders disagreed with their classification, they could challenge it, she said.
''That's going to be really important if you are looking for a consent in terms of increasing your cow numbers or establishing a new dairy farm or intensive winter grazing.''
Policy 16 - farming activities which affect water quality - was another important one for farmers. It covered minimising adverse environmental effects on waterways, Ms Gilroy said.
She highlighted the changes to intensive winter grazing to 15% of the landholding or 100ha, whichever was the lesser.
Cultivation was another one, along with the need for farm environmental management plans.
''There's now a greater focus on actions, rather than the written plan. So ... [it is what] people are going to be doing day to day that will make a difference and [the plan] is more focused on the contaminant pathways.''
She also covered changes to stock exclusion, feed pads and effluent storage rules.
Questions were raised from the floor regarding Farm Environmental Management plans and whether industry plans would be up to standard, which was acceptable as long as they met the requirements of Appendix N, Ms Gilroy said.
