McClutchie also claimed that, unlike, Apuwai and Yardley, he did not brandish a knife during the raid.
Getaway driver Sharna Harmony Mihaka, 19 at the time and who had no previous convictions, was remanded on continued bail for sentence on January 20.
Defence counsel Nicola Graham said Mihaka denied Crown claims she was "scoping" the shop when she made a purchase shortly beforehand, and only learned of her associates' robbery plans after she left the store.
But she then waited outside in the vehicle while the three men robbed the sole attendant in the shop of cigarettes and other tobacco products, and cash, with a total value of about $3500.
The robbers left in a blue station wagon which was stopped soon afterwards by police on the Hawke's Bay Expressway.
Judge Rea used a "starting point" of five years jail before calculating each sentence, giving credit for the robbers' early guilty pleas which meant there was no need for a trial.
