Two former champions have been confirmed for this summer's ASB Classic tennis tournaments.
Agnieszka Radwanska, the 2013 women's winner and former world No. 2, and 2016 champion men's Roberto Bautista Agut will return to Auckland in January.
A former Wimbledon finalist, Poland's Radwanska is currently ranked 11th in the world.
"I have never lost in Auckland so I have very good memories," she said.
"It always amazes me that the crowds are full right from the start. You don't get that at a lot of tournaments and makes it a great place for us to play."
Spain's Bautista Agut is ranked 13th in the world and has had another strong year on tour winning two ATP titles (Chennai and Winston Salem).
"For me Auckland is great to start the new season and prepare myself for Melbourne. I like the court and have played very well there. Maybe I can win another title," he said.
More big names are expected to be confirmed for the tournament.
"What is most exciting for me is we do not expect either of these two players, at 11 and 13 in the world, will be our top seeds," tournament director Karl Budge said.
The 2018 ASB Classic will span two weeks; the women's tournament running from January 1 to 6, followed by the men's tournament from January 8 to 13.
