This is a bit fuzzy.  How do you define a unit?  Is it a farm, or do the crops
have to be alternating within a small paddock?  What about shelterbelts?  
Small woodlots?

Why indigenous?  In NZ we grow exotic grasses with exotic conifers.  Does this
not qualify as agroforestry?  Why multipurpose?  Would alternating rows of
grass used for forage and trees used only for timber qualify?

This can be better achieved in NZ by farmers growing small woodlots rather
than pasture under trees, according to recent data.  They can diversify their
products by planting appropriate parts of their farms in trees.  This is
certainly "farm forestry", but perhaps not "agroforestry" according to Mair's

It would seems that you prefer a narrow definition, requiring intimate
associations of indigenous crops before you would label a production system
