Three people have been arrested after police followed their noses during a routine bail check in Invercargill.
Southland Area Commander, Inspector Mike Bowman, said officers were conducting a routine bail check shortly after midnight, and when an occupant of the address opened the door, officers were met with a strong smell of cannabis.
A warrantless search was then initiated under the Search and Surveillance Act 2012.
As a result of the search Police located drug utensils, a knuckleduster, small quantities of cannabis and methamphetamine, and around $12,000 in cash.
Insp Bowman praised the officers involved and said it proved the value of routine police work like bail checks.
"This started as a routine visit to a property for a bail check, but resulted in the arrest of two gang members and a gang prospect.
"To recover the drugs and other items as well is a real bonus, and a reminder to those who commit offences that police will hold you to account," Insp Bowman said.
The three men - aged 28, 29 and 45 years old - were arrested on driving, weapons, and drug charges.
Further enquiries are continuing.
