"The Kaimanawas coming out of the muster are true wild horses who have never been in contact with humans," Michele Hautain, KHH welfare officer said.
"In time they will do anything their owners ask of them, but in the early days they need sympathetic handling to ensure they make a successful transition to domestic life.
"Kaimanawas have an X-factor, their senses are acute, and they have proven to be very trainable. Given the right environment they are very curious, honest and friendly and are suitable for a variety of equine disciplines.
"Any mustered horses which do not find homes are, very sadly, destined for slaughter," Hautain said.
KHH said it was more than happy to offer prospective new owners with support and advice.
Closing date for applications is Monday, April 1.
The cost for taking a Kaimanawa from this year's muster had been set at $250.
This cost includes initial property check, transport from the muster site to a central pick-up point and membership and registration of the horse with KHH.
A gelding rebate of $75 was also available to new owners who took colts.
