This will be Jamie How's last first-class games in Auckland, the long-serving CD batsman having announced his retirement.
Auckland are without Craig Cachopa, who has a shin injury, his place going to Robbie O'Donnell. They sit top of the ladder courtesy of a five-wicket win over ND and a low-scoring win over Wellington, Colin Munro's 59 the highest score in the match.
Seamers Michael Bates and Matt Quinn split 12 wickets in that game. Confidence is up too.
"We've made a great start but we want to make sure that we ... head into the break still on top of the table," Auckland coach Matt Horne said.
Brendon McCullum makes a rare domestic first-class appearance for Otago against Canterbury at Rangiora.
Points after two rounds: Auckland 33, CD 24, ND 24, Canterbury 21, Wellington 21, Otago 5.
What's happening
• Auckland look to cement their lead against second-placed Central Districts at Eden Park starting today.
• New Zealand captain Brendon McCullum makes a rare appearance for bottom side Otago against Canterbury at Rangiora.
