"We need a good amount of rain in the next couple of weeks or else it will become serious."
There was no shortage of feed at this stage after farmers had good harvests in November and December following 80-100mm of rainfall dumped on the region.
There was also a good supply of palm kernel to use.
"The spring and early summer harvest set us up but if the hot weather continues we may have a problem."
There had been no reports as yet of farmers drying off cows.

Farms north of Rotorua were not experiencing the same dry conditions, said Paradise Valley sheep and beef farmer Neil Heather.
"It's not too bad here, the soil moisture is good, and we don't normally get the same conditions the farms further south have."
After devastating droughts several years ago, many farmers put in contingency plans, such as feed silos, to be better prepared, he said.
