I see you're in New Zealand. As there are two breeds of small lop recognized there (Dwarf Lop and Mini Lop) they are probably Dwarf Lops as they don't have those little fat squishy faces the minis have. They won't be French Lops as they are about double the size of yours.
I'm in the UK but my two are Dwarf Lops and look like your two cuties.
