Smith had back-to-back wins in the open shearing finals at the Dannevirke A and P Show on Friday and then at Marton on Saturday.
This success repeated similar efforts at Wairoa and Levin a fortnight earlier, and at Taihape and Rotorua last week.
Reigning world champion woolhandler Henare also enjoyed a double win at Dannevirke and Marton on Friday and Saturday.
Henare will be out to claim a shot at defending the big title when a selection series final is held at the Golden Shears in Masterton next month.
