A 76-year-old man has been arrested for importing cocaine.
The man was taken into police custody alongside a 25-year-old woman after police searched a Christchurch property on Friday.
Cocaine and a "significant" amount of cash were found.
The search followed a bust in late March where customs intercepted a package containing 1.5kg of liquid cocaine.
"This is another example of Police working collaboratively with Customs in order to prevent the devastating harm created by the sale and supply of illicit drugs," Detective Senior Sergeant Joel Syme says.
"Police will continue to target this type of offending, alongside our partners, in order to keep our communities safe."
