Canterbury's position atop the Plunket Shield domestic cricket has extended following the failure of their main rivals yesterday.
Northern Districts and Wellington had a chance to close the gap on the runaway leaders.
But neither side could get over the line in a fascinating final day.
Northern Districts came into the round in second and were set 330 to win in 85 overs by Auckland after Glenn Phillips brought up his maiden first class century.
In the process, Phillips became the first player to record a century in all three domestic formats in one season.
