Auckland's bowlers were economical and the constant tumble of wickets, largely in part to the left arm pace and spin duo of Michael Bates and Bruce Martin, kept the Aces in the game.
On day four the match remained in the balance as Central Districts led by 281 runs but with only three second innings wickets in hand. However, Black Caps tailenders Doug Bracewell (36) and Adam Milne (29*) helped push the overall lead to 348 runs with some sensible batting. Bates and Martin both finished with four second innings wickets with swing bowler Bates collecting figures of 4-31 from 22 overs, including 10 maidens.
The Stags bowlers had their chance with 72 overs left in the day to dismiss the Aces for the second time in the match.
Auckland crumbled early under a probing spell from Ben Wheeler who removed both openers, including the in-form Guptill for just five.
Loosing wickets at regular intervals, Auckland's hopes of salvaging a draw were all but dead at 73-6 after 38 overs. But former Black Cap batsman Tim McIntosh, who replaced Anaru Kitchen for the match at the crucial No3 slot, formed a defensive wall with fellow spinner Bruce Martin to deny the Stags for the remaining 34 overs.
The pair made an unbeaten 101 runs for the seventh wicket, but more importantly soaked up 400 minutes and 309 fruitless CD deliveries.
Stags assistant coach Lance Hamilton said he was "disappointed" and "frustrated" not to come away with more than just a few bonus points after having Auckland five down early on.
"It was a typical Nelson Park day four wicket, very flat and once they lost a few early wickets they were just blocking and playing for the draw.
The Stags would have backed themselves to win if they had broken the century stand, knowing only tailenders Michael Bates, Mitchell McClenaghan and Dean Bartlett remained in the shed, none of which are heralded for their batting.
English import Trego capped off an impressive match with 2-26 from nine overs as he tried desperately to force a mistake from the veteran Aucklanders who finished on 174-6. Wheeler was the only other bowler to enjoy some success yesterday with 2-30 from 14 overs, while Black Cap and Taradale allrounder Doug Bracewell went wicketless from 16 overs.
Hamilton who was pleased with the effort his bowlers showed.
Central Districts walks away from the game with eight competition points, while Auckland picks up seven. Neither side has won a match from five attempts so far and fill the bottom two spots on the competition ladder.
