Farmers around the North Island are being warned to prepare for drought conditions as the late summer dry period continues.

In Taranaki, it's being described by some as a one-in-fifty-year event.

Local vet Stephen Hopkinson sits on the Taranaki Rural Co-ordination Group which is working with the region's Rural Support Trust to help farmers.

He said those in the south of the region near Hāwera and Manaia are facing "desperate conditions".

"It's unusual for Taranaki, we get dry summers and we've had the odd minor drought declaration in the past but this would be one of the worst ones.

"We're running into water issues, water tables are so low, people's wells and bores are drying up and losing water supply.

"We've never had water issues before so that's compounding it this year and is another big complication."

Stephen Hopkinson said the events have been attended by more than 100 farmers as the majority of the region is now drying out.

He said culling and drying off stock, and budgeting for feed are just some of the issues farmers are grappling with.

The Rural Co-ordination Group expects to hear back in the next fortnight from MPI about whether a drought will be declared.

And the Taranaki Rural Support Trust chair Amanda Jordan says farmers need to check in on each other and anyone who needs help can call the trust's 0800 number.

In Whanganui hill country farmer Grant Adkins said the region hasn't had a dry spell for a couple of years so people are out of practice at dealing with the situation at hand.

He's getting down to capital stock by sending store lambs away and killing cattle.

He said some farmers won't have any supplementary feed left.

"We've got enough feed cover to carry on for another month if I have to but there's farms out there that don't have that, and that's a worry.

"People need to be proactive and if they're not sure, ring someone and get a second opinion but the worst thing you can do is carry on and let your livestock lose condition because then they're not saleable."

Grant Adkins said he's keeping a close eye on the forecast because he will be extremely concerned if there is another month with no rain.

And he's following market trends with prices so far holding up, which he says is remarkable for this time of year.

"If there's a question should I sell or not, in my mind selling while the money's good is certainly worthwhile."

Niwa maps of the area already show rain levels are well down on the long term average.

Manawatū dairy farmer James Stewart says warm easterly winds have dried pastures out.

He says feed supplies are getting short and irrigators are running.

"Farmers will be starting to action their plans to reduce their cow numbers like cull cows as we go into the autumn.

"I think with a higher payout we've got the ability to even purchase in supplement [feed] without too many concerns."
