Sparse reports highlight a single instance of an unsolicited call from an unfamiliar number, leaving no voicemail and raising spam flags, especially for recipients outside New Zealand. This pattern suggests possible telemarketing or nuisance attempts targeting international lines. Block the number immediately to prevent repeats, and register with local do-not-call lists like Australia's Do Not Call Register for added protection. Enable caller ID apps to screen unknowns, and report suspicious activity to authorities if calls persist—better safe than sorry with cross-border unknowns.
A caller I didn't recognize left no message, which seems like spam. I'm Australian and wasn't expecting any calls from NZ.
