Why not call them the Penrith Warriors then...if you want to keep narrowing down their fanbase to their actual base ?
Let me explain to the retards. The Warriors are the only NZ team in an Australian comp...therefore it's quite logical that they are named thye NZ Warriors FFS. Not rocket-science
Should another NZ based team (from Wellington or Canterbury for example) ever be admitted into the comp, then yeah...they lose the NZ Warriors tag and go back to Auckland Warriors
