Calls from international numbers like this, especially without voicemails, often signal unwanted intrusions. Picture this: your phone buzzes repeatedly from an unfamiliar NZ line while you're in Australia, leaving you suspicious and annoyed. Such patterns scream spam or phishing attempts, where scammers probe for responses to harvest data or push scams. Block the number immediately on your device to stop the harassment. Enable spam filters in your phone settings or apps like Truecaller for better protection. If calls persist, report to authorities like the ACCC in Australia or Do Not Call Registry. Never engage or share info—silence is your best defense against these nuisances.
Based in Australia, I keep receiving NZ calls with no voicemail; clearly spam or phishing.
