At the SJNZ Conference 2009, The Showjumping New Zealand Board addressed Article 147.1 of the ESNZ General Regulations, this rule states that;
All horses must have an ESNZ approved ID Tag which must be worn during the whole event at all times
It was agreed that as of the 1st September 2009 all horses competing in registered showjumping events will need to display a Horse Identification Number.
SJNZ has decided, with consultation from senior showjumping riders, that the Zilco numbering system will be used. Each Show Secretary will provide each horse with a three digit number. This number can be displayed easily as shown below. These numbers can be purchased from ESNZ or your Zilco Stockists.
