Auckland made an acceptable start in their attempt to climb the Plunket Shield standings, limiting a fast-starting Canterbury for day one honours.
Canterbury were 19 points ahead when the day began and, with a win worth 12, victory would enhance Auckland's chances of claiming a prize they last secured in 2009.
Having restricted the leaders to 255-7 at stumps at Hagley Oval in Christchurch, Auckland have already claimed three bowling bonus points and will have designs on grabbing the fourth today.
It didn't look that way early, as Canterbury's top three all made solid starts after Gareth Hopkins won the toss and elected to bowl. With the new ball seen off, it was left to Auckland's allrounders to make the breakthrough, which duly arrived when Colin Munro trapped Tom Latham in front for 39.
Michael Bates got rid off fellow opener George Worker, before Colin de Grandhomme chimed in with the wickets of Dean Brownlie and Henry Nicholls.
