"My fourth goal really showed what this team is all about this year. We dominated possession for a long period and I was able to tuck away after a lovely team move."
Ngongotaha took the lead in the sixth minute thanks to a Josh O'Sullivan strike in the box.
The away side were then 3-0 up after 33 minutes thanks to two Miller strikes in five minutes.
And Miller calmly finished his hat trick five minutes later, neatly tucking away a shot with his left foot after Old Blues failed to clear their lines.
After the break captain Dave Haua extended his side's lead in the 55th minute of the game.
Miller then grabbed two more goals in the space of five minutes, with his fourth of the match being the most impressive - the potent striker latching on to a wonderfully chipped through ball from midfield in the 75th minute of the game.
To add insult to injury Old Blues then scored an own goal six minutes from time to seal a crushing defeat.
The result sees Ngongotaha remain at the top of the WaiBOP Premiership on 31 points - with a three point gap between themselves and second-placed Matamata Swifts with a game in hand.
Meanwhile, Rotorua United drew 2-2 against Katikati FC Ambria with United goals from Ash Gower-Rudman and Ian Wilton not being enough to grab all three points.
