Labour's plan to separate supermarket wholesale and retail, explained
Labour would require Foodstuffs and Woolworths to run their wholesale operations separately from their supermarkets if it wins November's election.
The policy would create two separately managed wholesalers, Foodstuffs Wholesale and Woolworths Wholesale. Labour says separate operation would give smaller grocers more places to buy stock and make it easier for new supermarkets to open and grow, according to RNZ.
Commerce and consumer affairs spokesperson Arena Williams is fronting the proposal. The mechanism is operational separation. It is like one owner with two teams. Wholesale and retail would stay under the same ownership but run at arm's length, with separate management and commercial incentives.
Labour says that separation would stop wholesalers cutting off supply once smaller retailers start winning customers. The rule would work as a non-discrimination obligation. In simple terms, size and volume would not decide who gets access.
The plan would also remove restraint of trade provisions inside the existing networks. Labour points to stores such as Four Square. It says those restraints currently stop members from discounting below set levels, switching banners, or leaving to trade independently.
The proposal builds on the last round of grocery intervention. The previous government required Woolworths and Foodstuffs to reach wholesale supply agreements with rival retailers or face regulated wholesale pricing set by government. That ultimatum produced negotiated supply deals rather than direct price control.
Labour says those deals did not fix the underlying incentives. Its case rests in part on the Commerce Commission's wholesale review earlier this year. The review found Woolworths had strengthened its wholesale offer, including through a dedicated wholesale business. It found Foodstuffs North Island had made small improvements, while Foodstuffs South Island had been slower to act.
On outcomes, the Commission found competition remained weak. It said pricing, range and access had not shifted far enough to support sustained independent retailing. Labour says that finding points to a structural remedy rather than another round of monitored supply terms.
National is campaigning on a different intervention. It has vowed to break up Foodstuffs if re-elected, a retail-level split rather than a wholesale separation. Under that plan the Commerce Commission would get six months to assess whether the break-up could be done, according to RNZ.
The distinction matters for officials and for the sector. Labour would intervene at the wholesale layer and apply the rule to both major groups. National would intervene at the retail layer and target the Foodstuffs co-operative model specifically.
The broader context here is the choice between regulating conduct and restructuring incentives. Wholesale separation starts from the idea of vertical integration, where a wholesaler that also owns shops has reason to favour its own stores on price, range or service. Separate management, separate accounts and limits on shared information are meant to remove that incentive without changing who owns the stores.
In my view, the questions political staff and policy advisers will test are definitional and practical. What counts as independent in day-to-day buying, transport and product range decisions. How the ban on supply cut-offs and the removal of restraints are written and enforced. And whether two wholesalers, both still linked to the incumbents, can offer enough range and national distribution to support genuine new entry. Those are implementation issues, but they will determine whether the policy reads in the Beehive as competition reform or as a compliance exercise.
