A male prisoner has escaped from his job at a horticulture nursery at Rimutaka Prison.
Police were alerted at about 3.15pm yesterday that an inmate at the Upper Hutt prison had left the jail in a vehicle, a spokesman said.
"Police are making inquiries to locate him," he said.
Lower North Regional Commissioner Paula Collins said corrections was working with police to track him down.
"As soon as staff were made aware of the incident the prison was locked down immediately and Police were requested to attend as a priority," Collins said.
