The order's applicants are concerned about land use change being a threat to the water quality, which is one of their reasons for a WCO. However, we will be pointing out change is always occurring, and it's not the threat they think it is.
Water quality of the Ngaruroro is very good, proving farming and water quality can exist side-by-side.
E. coli concentrations are almost all within the "A-band" of the National Objective Framework under the National Policy Statement for Freshwater Management.
As for land use, short term change happens constantly with the seasons. Long term change has been moving away from a monoculture of sheep and towards a diversity of production including beef, grapes, olives, arable and growing.
There is little risk of wholesale conversion to dairy. There isn't enough natural rainfall for the kind of grass growth cows need and irrigation is limited by terrain.
The irrigation we do have is mainly for lamb grazing over summer, and for crops like maize or vegetables.
We already have rules and regulations for water quality in the Hawke's Bay, so it's not like the Ngaruroro is unprotected.
These rules are even being reviewed at this very moment under the TANK project for the Tūtaekurī, Ahuriri, Ngaruroro and Karamū rivers.
