Police are appealing for witnesses to an incident where shots were fired at police and an aggravated robbery took place in Manawatū and Horowhenua on January 4.
Acting detective senior sergeant Dave Thompson says police are still piecing together a series of events and believes there are members of the public who may hold vital information.
"We are specifically interested in speaking with people that saw two vehicles being driven erratically," Thompson said.
"The first was a silver Mitsubishi sedan on the Foxton township and the second was a green Mazda Demio which travelled from Foxton before carrying on to the Feilding area."
Thompson said police are continuing to offer support to the woman who was the victim of aggravated robbery after her car was stolen during the incident.
"She handled herself extremely well in a very stressful situation and we commend her for this."
"Sadly the repercussions are ongoing for her. Not only did she have to face this overwhelming situation, but the vehicle she depends on has been damaged beyond repair and was not insured."
A 30-year-old man has been charged with using a firearm against a law enforcement officer, aggravated robbery, possession of a pistol, and a number of driving offences, in relation to the incident and is now in custody.
Police are asking anyone who has information regarding the incident to call 105 and quote file number 210104/6343.
