The sibling comment made a great point about no huge outbreaks in package/mail sorting facilities, but the article you linked to from NZ about the two people who used the elevator is begging the question.

What we know is that a worker got in the same elevator as an infected person "only a matter of minutes" after the infected person used it. They say that it most likely would have been from a contaminated surface, but the only reason they are saying that is because the WHO guidance doesn't acknowledge aerosol transmission.

If you look at this one datapoint, it is very interesting that the one place where they're getting "fomite" transmission is about the smallest enclosed space that exists in a building. Fomite transmission could happen on any number of shared surfaces, but it just so happens to occur in an elevator for some reason, not the people washing dishes in the basement.
