New Zealand Express was a company created to be an express forwarder of parcels, both throughout New Zealand and overseas. Set up in 1877 under the name Campbell and Crust, in 1895 it changed its name to New Zealand Express. The company seems to have had a good working relationship with New Zealand Railways which apparently included special drop boxes on certain trains, and parcel transfer arrangements.
This set of five value stamps appeared sometime in the last few years before the turn of the century. They were used in much the same way as similar NZ Railways revenue stamps, to show payment had been made on items being transported. The stamps ranged in value from ½d to 6d. Later another 1/- appeared in a different design and larger format.
