An hours-long standoff at Christchurch Men's Prison is over after the final three prisoners surrendered to Corrections officers.
Seven prisoners were originally involved in the standoff, after they were escorted to a yard for recreation time around 8.30am,
They refused to go into the yard but would not return to their cells, Southern Regional Commissioner Ben Clark said.
About 10am four of the prisoners had surrendered and were secured, but the remaining three held out for another three hours before giving up.
Clark said earlier that staff were trying to calm the remaining prisoners down, and they were not being aggressive.
