A 29-year-old woman and a 22-year-old man were jointly charged with possession of cannabis, cocaine, MDMA, ketamine and LSD for supply.
Both were granted bail.
Cannabis seized by police in Hastings last week.
A pump-action shotgun seized from a Hastings address last week.
A sawn-off shotgun seized during the raid.
All three are due to reappear on September 1 in Hastings District Court.
Detective Senior Sergeant Karli Whiu said the seizure would have a significant impact on the availability of harmful drugs in the community.
“The combination of illicit drugs, firearms and large amounts of cash highlights the risks associated with organised crime offending.”
While the seizure was significant, what concerned police most was that young children were living in an environment where drugs, firearms and ammunition were present.
“Police will continue targeting those whose offending puts both the community and children at risk.”
Police were continuing their inquiries, with further charges possible.
Anyone with information about the supply of illicit drugs is encouraged to contact police via 105 online or by phone.
Information can also be provided anonymously through Crime Stoppers on 0800 555 111.
