	Just looking at the MPI regs, if she were quarantined on arrival it would only be if she came from a country where the below are present. I also don't see any requirement to test for piro during that quarantine? Or post-arrival?
 
	(3)When equids are to be imported into New Zealand from countries where the diseases listed below are considered present,the duration and type of PAQ is stated in brackets: 
 
	a)Equine infectious anaemia (EIA) if considered by MPI as moderately to highly prevalent in the country of export (minimum 7 day PAQ)
