Northern Districts had a decent day with the ball against Auckland, who ended the day at 322-9.
Missing the dominant Colin Munro after his one-game suspension for inappropriate language, Robbie O'Donnell top scored for Auckland with 75. At 159-5, they looked in a spot of trouble, but middle-order contributions from Mark Chapman (48) and Tarun Nethula (52) stabilised the Aces' innings. International contenders Ish Sodhi (2-87) and Scott Kuggeleijn (4-75) bowled effectively for ND, as did all-rounder Daryl Mitchell, who claimed 3-40.
Wellington also had another international contender boost their hopes, with Luke Ronchi rescuing the men from the capital.
Reduced to 62-5 after a superb spell from Seth Rance (4-61), Ronchi made 70 in a 104-run stand with Peter Younghusband as the Wellington tail wagged to reach 245 all out.
Central Districts' powerful batting lineup was at 5-0 at stumps.
