Police have arrested a fourth person in relation to a fatal shooting in Taita.

39-year-old Adam Watkins was shot dead in the Lower Hutt suburb a week ago.

A 19-year-old woman has been charged with his murder, and a 40-year-old man charged with helping her avoid arrest.

A third man, aged 29, is facing an accessory to murder charge.

Now police have arrested a fourth person - a 38-year-old Hutt Valley woman charged with attempting to pervert the course of justice.

Detective senior sergeant Warwick McKee says the latest arrest provides reassurance to the family of Mr Watkins and the Lower Hutt community.
