Elsewhere, Canterbury struck three times late in the day to edge near parity in their match against Central Districts at Saxton Oval. Canterbury, the closest challengers to the two table-toppers, also struggled through their first innings with the bat, being dismissed for 204 as Navin Patel took 4-37.
Only Peter Fulton (89) enjoyed his outing, with the Canterbury captain the last man out as Patel denied him a shot at his 19th first-class century. In reply, though, Central Districts suffered similar difficulties, slumping to 52-3 at stumps after Kyle Jamieson and Todd Astle combined to take three wickets in the final eight overs.
It was a similar story at University Oval, with ball again dominating bat as Otago welcomed Northern Districts. Brad Wilson struck 97 as the visitors were bundled out for 237, with James Baker dismissing the opener agonisingly short of recording three figures against his former team.
But after Baker (3-42), Scott Kuggeleijn (3-72) and Tony Goodin (4-50) had put their side in a strong position, the batsmen were unable to reap the rewards as the home side reduced ND to 53-2 at the close of play.
