A fourth person has been charged after a spate of aggravated robberies in Christchurch in the past month.
Three men, aged 18, 35 and 38, appeared in the Christchurch District Court on Saturday facing a variety of charges including aggravated robbery and burglary.
Today, the three men and one woman, aged 36, will appear in the city's district court.
The men are charged with aggravated robbery and burglary. The woman has been charged with receiving stolen property.
Detective Inspector Craig Scott said the arrests come after a police search at an Edgeware address last week.
