The 1969–70 Plunket Shield season was a tournament of the Plunket Shield, the domestic first-class cricket competition of New Zealand.
Otago won the championship, finishing at the top of the points table at the end of the round-robin tournament between the six first-class sides, Auckland, Canterbury, Central Districts, Northern Districts, Otago and Wellington. Ten points were awarded for a win, five points for having a first innings lead in a draw and one point for a first innings deficit in a draw. The match between Otago and Northern Districts was rained off before both teams could complete one innings each resulting in both teams gaining three competition points.
