NZ Post review: The worst service in NZ

NZ Post is, without question, one of the worst companies I have dealt in New Zealand. Over the past year, I have had around five separate problems with them. One parcel was delivered to the wrong address. On two other occasions, my parcels never arrived at all. In another case, I paid for MZ Post's mail redirection service and did not receive a single redirected letter. Not one in 6 months.
What makes the whole experience even worse is the customer service, Its absolutely appalling. If you make a complaint through their own website, nothing happens, Emails are ignored, there is little or no follow-up, and you are left chasing them for problems that were boused by their service in the first place. I struggle to understand how a national postal service can operate this badly. I have experienced postal services in many places, and NZ Post honestly feels lees reliable than services you would expect in countries with fare fewer resources. We constantly hear about organisations being restructured and services being reviewed in order to improve efficiency and customer outcomes. So why does nothing seem to improve at NZ Post? NZ Post becomes progressively worse. Delivery reliability is poor, accountability seems almost non-existent, and the complaints process appears completely ineffective.
