Not in New Zealand, or most countries for that matter.
Twins can also fail, and from experience twin engine pilots are sometimes even less (mentally) prepared for an autorotation than single engine drivers. Reference: the same Glasgow pub crash I linked above.
Twins are as prone (or more) as singles to some of the following problems: gear box failure, rotor system failure, in-flight breakup, fuel starvation, CFIT, pilot error in general.
