"This was a local drug ring where offenders operated out of suburban homes in both cities. They have created a major drug problem in Hawke's Bay and we are determined to take a hard line on anyone who engages in this type of illegal activity.
"They are doing massive harm to our community and it's important that we stamp out this drug trade and hold those responsible to account," Mr Pritchard said.
The psychoactive substances seized are a leaf or herbal extract and are laced with household cleaning products and other chemicals. They were "extremely hazardous" and essentially poisonous.
Napier community police say they have grave concerns for the health and wellbeing of their young people, who are being targeted in the sale of illegal psychoactive substances.
Sergeant Cam Donnison of the Maraenui Neighbourhood Policing Team said police were regularly dealing with teenagers, many as young as 11 and 12, who were using the drug regularly and developing habits.
"This drug is having a major impact on the health of our kids - they are literally walking around like zombies and can't focus on anything. Police and other agencies have come across kids lying on their backs and shaking, just like a fly that has been sprayed with fly spray.
"These substances are doing incredible damage to these kids' brains and are sucking the life out of them," Mr Donnison said.
Mr Donnison believes the drug suppliers are targeting young people because they are vulnerable, easily influenced and will not resist the aggressive approaches from dealers to buy the drug.
As a result, burglaries and other crime had increased markedly in the area due to young people trying to finance their drug habits.
