The answer is
the "plum pudding" model of the atom (an extended positive blob with small electrons spread about in it like raisins in a plum pudding) was made obsolete ("retired") by Ernest Rutherford's experiments shooting alpha particles at gold foil
one can parse it as PLUMP (big) + DIN (noise) inside UDG (dugout = DUG out = anagram of DUG).
I think it's actually the $100 note.
I think the title
is deliberate misdirection, because for some readers the most notable New Zealander called Rutherford might be this guy or even his son Hamish, both of whom are batsmen.
