Williams has 23 grand slam singles titles to her name, since winning her first major way back in 1999. That's one short of Australian Margaret Court's all-time record of 24, which Williams is desperate to match.
She reached the final at Wimbledon and the US Open last year — becoming the oldest grand slam finalist in the process — but fell short on both occasions, losing to Simona Halep and Bianca Andreescu.
That's a big part of the reason why she has come back to Auckland, despite the unhappy memories of her shock second round exit to unheralded compatriot Madison Brengle in 2017.
The Brisbane WTA event would have been another option, but has a stacked field (six of the world's top ten), and there is more chance of a run of matches at the ASB Classic, as long as she can find some early rhythm.
She also enjoyed the friendly, but low-key atmosphere in the Queens city on her previous visit.
Budge said Williams hasn't made any special requests for sightseeing trips, or helicopter rides, like some high profile players have enjoyed in the past.
"She won't do too much while she is here," said Budge. "It's a very business-like Serena this week. She has come here with a big team that can make sure life off court is taken care of and she can focus on winning tennis matches. She made two grand slam finals last year, but she wants more than making finals."
"I think you will see an incredibly motivated Serena Williams go deep here at the ASB Classic and take that form into the Australian Open."
Williams, currently ranked No 10, will be top seed at the tournament, which begins on Monday.
