The 26-year-old smacked 16 fours and five sixes in the Blues' seven-wicket win over Victoria at North Sydney Oval on Sunday.
His second ton of the Australian domestic summer came three days after his 139 against Queensland at the same venue.
Warner's return to form ends a horror run both on and off the field in 2013 after a string of low scores and off-field indiscretions - including being handed a two-match suspension for punching England batsman Joe Root in a pre-Ashes nightclub incident and a one-game suspended ban for missing a NSW grade match to go to the races - threatened to derail his career.
"I've had a tough trot but I'm just happy to score runs for NSW, I'm enjoying playing cricket," he said.
Warner's explosion of runs sends a strong message to Australia selectors after he was controversially left out of the national Twenty20 and one-day sides for the current tour of India.
Asked if he has been keeping an eye on the seven-match ODI series against India, Warner eluded to his more disciplined lifestyle as he looks to get his career back on track.
"I'm in bed mate, 8.30 at night," he said.
"It's good to see the Australian boys winning but I'm here at the moment to score runs for NSW and I'm doing the job.
"From the get-go, I've been feeling good. I've been playing very well in the nets but you can't get them in the nets - you've got to come out and perform.
"I just backed myself and played my strokes and it's good to see the boys, all of us, gelling together and playing so well."
Warner will be back in action for the Blues in a Ryobi Cup clash against South Australia on Tuesday at Drummoyne Oval.
He also has three Sheffield Shield matches and a possible tour match for NSW against England in preparation for the first Ashes Test in Brisbane starting on November 21.
