A Waikato horse trainer has pleaded guilty to charges of importing performance-enhancing drugs.
Nicola Chilcott, 41, appeared in the Hamilton District Court on Friday on four charges brought by the Ministry for Primary Industries, of breaching the Agricultural Compounds and Veterinary Medicines Act 1997.
Chilcott brought the compounds ITPP and TB-500 which can be used to dope horses into New Zealand in March last year.
Four others charges under the Biosecurity Act were dismissed.
The prosecutor for the ministry told the court that before sentencing, it will need to hear from expert witnesses about the significance the compounds have for the racing profession.
Chilcott's lawyer Warren Scotter said the charges are a relative non-event and claims of horse doping are misleading.
The case will return to court in March for a status hearing.
