Customs has intercepted 70 weapons including pepper sprays, stun guns, rifles and knives in Tauranga over the past two years.
Information released to the Bay of Plenty Times under the Official Information Act shows weapons, objectionable material, drugs and endangered species are among items Tauranga Customs staff have seized since the start of 2012.
During that time three weapons were found during two air cargo searches, 16 were found when two lots of mail were intercepted and 51 weapons were found as a result of 12 sea cargo searches.
