Venus, a seven-time Grand Slam winner, will still be enough to aid in attracting fans and fellow players alike, with tournament organisers hopeful of approaching the heights of last year's showpiece match.
"That final last year for us was as good as it gets," Budge said. "Any tournament around the traps, let alone an international-level tournament, would be absolutely delighted to have that final."
Williams enjoyed a good year after Auckland, reaching four finals and winning her 45th career title, and said via video message she was happy to be heading back.
"I'm so looking forward to coming back to Auckland, taking it a step further this year and hopefully winning the title," she said. "I had such a great time last year. Everyone made me feel so at home - I really felt like a Kiwi."
