Since wipers attach to bottom of windshield that is a clue. I saw a 1974 HJ45 with wipers attached to top of windshield. If front brakes are disc, the vehicle is no older than 1976. Toyota shifted to HJ47 with 2F motor in 1980.
That is an interesting stamping on the VIN plaque. Instead of the model number the VIN is stamped and no place for the VIN towards the bottom. Thought New Zealand got Australian models. Those have a second locally produced tag.
