Kvitova won the second WTA title of her career in Brisbane
Czech Petra Kvitova defeated Andrea Petkovic of Germany to win the Brisbane International final, 6-1 6-3.
Kvitova controlled the match from the outset and was rarely threatened on her way to a second WTA Tour title.
The Wimbledon semi-finalist and world number 34 now heads to the year's first Grand Slam at the Australian Open.
Meanwhile, Hungarian Greta Arn shocked champion and second seed Yanina Wickmayer of Belgium 6-3 6-3 to win the Auckland Classic final in New Zealand.
The 20-year-old Kvitova claimed the second WTA title of her career with the 71-minute win, adding to her victory in Hobart in 2009.
Petkovic, ranked 32 in the world, was never able to settle in the face of Kvitova's power and accuracy.
"I played very well here and had some tough matches so I now have a lot confidence and hopefully I will also play well in Melbourne," she said. "We'll see which round I get to."
In Auckland, 31-year-old Arn, who knocked out three seeded players on her way to the final including Maria Sharapova, won the title with similar ease.
The world number 88 was steady rather than explosive and helped by Wickmayer's numerous unforced errors, saying afterwards that the victory was a "dream come true."
Her only previous other WTA tour title came in Estoril, Portugal, in 2007.
Arn picked up her second WTA Tour title with the victory in Auckland
"The feeling, I couldn't believe it, I cannot describe it," she said. "That's what you've wanted and you've got it."
Arn beat eighth seed Sofia Arvidsson then caused the upset of the tournament when she easily accounted for former world number one Sharapova in the quarter-finals, before defeating fourth seed Julia Goerges to earn a place in the final.
Wickmayer, who had not dropped a set on her way to the title last year, had three three-set matches this week, against former world number one Dinara Safina, Sabine Lisicki and against China's Peng Shuai, with the semi-final against the Chinese on Friday lasting almost three hours.
"I had to come back a lot of times and I had to fight though a lot of difficult moments," Belgian Wickmayer said. "It makes it not easy to stay fit mentally."
