In a blender puree the mango, passion fruit nectar and lime juice until smooth. Strain through a mesh strain and set aside.
In a cocktail shaker full of ice combine 1 part vodka and 1 part of the mango and passion fruit puree. Shake and strain into a chilled martini glass. Repeat with remaining ingredients and garnish each glass with a piece of mango.
