"There are a lot of people I know who wait for the postie arriving - even if there's no mail - the postie's there and often it's just a wave or a 'hello'. It's a sort of human contact they have, which I think is very important. We are losing part of humanity by going into electronics."
Mr Turner said many older people, like himself "wouldn't have a clue about computers" and were not about to start learning.
Meanwhile, an advocacy group for rural women has expressed its concern for older people living alone.
Rural Women New Zealand national president Liz Evans said while the group understood NZ Post needed to address the dramatic decrease in mail volumes, the special role of the rural delivery service needed to be acknowledged and preserved as far as possible.
Mrs Evans said the service was a real lifeline for many people.
"Parcels posted to and from rural areas already incur extra costs and we would not wish to see further targeting of rural customers who are so dependent on the mail service.
"For some living in remote areas, the rural delivery contractor is the only contact with the outside world for days at a time. Several [members] mentioned how important this is in combating loneliness, which can lead to depression, another very real problem for rural areas."
The group would be further consulting with its members on the proposal and making a formal submission to NZ Post.
