Striding down the thoroughfare of Hurstville's Chinatown on Wednesday morning, NSW Treasurer Dominic Perrottet was in a jolly mood.

Lunch at a local yum cha restaurant had only been penciled into his schedule that morning, after Liberal Party strategists deemed a ministerial visit to the Labor-held electorate of Kogarah opportune.

Accompanying the Treasurer on his walk was Scott Yung, the Liberal candidate for Kogarah, who was happy to weigh in on the storm engulfing Labor leader Michael Daley.

"Michael Daley's comments are racist," Mr Yung said, as TV cameras encircled them. "I'm proud of my Chinese heritage."
