He works as a track rider for Logan Racing and has worked in the industry for 27 years.
The charges he faced related to a standard-bred, 10-year-old trotter mare and another 10-year-old thoroughbred flat racer mare.
Two SPCA officers visited a paddock on Marsden Pt Rd in Ruakaka on August 30, 2011 and found low and poor quality grass, an empty bathtub by a gate and four empty plastic half-drums.
One horse was thin and its hooves were overgrown.
Another animal was extremely thin, all the rib, hip and spinal bones were clearly visible. It had overgrown and cracked hooves and hair loss.
The animals were removed from the paddock on the advice of veterinarian Angus Campbell and taken to a foster property in Maungatapere where they went immediately to the trough and drank for several minutes.
Dr Campbell said thoroughbred mare was starved during a period of weeks and considered the animal wouldn't have survived any longer in the circumstances.
He said the case was on par with animals he had seen dying in extreme drought conditions.
The hooves of both horses were trimmed and both made a full recovery before they were returned to Allen.
In court yesterday, Judge Greg Davis said given Allen's extensive experience in the horse racing industry and his close proximity to the paddock where the horses were kept, it wasn't a burdensome task for him to look after the animals.
He said Allen's disqualification only from owning animals for one year wouldn't prevent him from working in the industry under supervision.
Allen was ordered to pay the SPCA reparation of $1583 for the cost of feed and veterinarian care.
He was also ordered to pay $452 for costs towards prosecution.
