Probably they just wanted to increase margins by closing physical stores and cutting-down staff.
In Australia the Wesfarmers group stores (Kmart, Target, Bunnings, OfficeWorks) have a OnePass subscription so you get free shipping and optionally Disney+, similar to Amazon Plus. The free shipping is just too addictive, and once you get your "free-shipping" subscription you cannot avoid buying stuff you don't need.
NZ companies just don't seem to be able to make it over in Oz. So many have tried, including TWH. But Australian companies coming to NZ seem to do pretty well. The market did have free shipping for paid memebers, but it was quite limited and a minimum spend, and didn't apply to all sellers, which IMO was a big problem.
