Layout decisions in a fast-moving consumer goods (FMCG) distribution centre carry consequences that a general warehouse does not face. Short-dated inventory, high stock-keeping unit (SKU) counts and strict first-in, first-out (FIFO) rotation requirements create design pressures that generic storage layouts are not built to handle. A facility optimised for throughput velocity, FIFO compliance and seasonal flexibility performs differently from one configured around storage density alone, and the difference shows in spoilage rates, pick accuracy, labour cost and customer service levels. The layout strategies, racking systems and zone design principles covered below determine FMCG warehouse performance in New Zealand distribution environments.
Why FMCG distribution demands specialised warehouse design
FMCG distribution centres operate under five pressures that generic warehouse design does not adequately address. Understanding these pressures is the starting point for making layout and racking decisions that hold up under real operating conditions.
- Throughput velocity: FMCG lines move fast and in high volume, placing constant demand on receiving, picking and dispatch operations simultaneously.
- High SKU counts: a large and dynamic product range requires a layout that provides accessible pick faces for hundreds or thousands of individual lines without collapsing aisle efficiency.
- Short-dated inventory: products with limited shelf life create spoilage and write-off risk if FIFO rotation is not enforced at both the storage and pick face level.
- FIFO compliance: stock rotation is a commercial and regulatory obligation for food, beverage and consumer goods businesses. Racking configuration must support it systematically, not rely on operator behaviour.
- Seasonal volume spikes: promotional periods and holiday peaks create demand surges that a fixed layout must absorb without operational breakdown.
A warehouse design that does not address all five of these factors creates operational risk rather than operational capacity.
Zone design: the foundation of FMCG warehouse layout
The four core zones of an FMCG distribution centre (receiving, bulk storage, pick face and dispatch) must be sized and positioned based on product flow, not available floor space. Poor zone adjacency is one of the most costly and least visible design failures in high-volume distribution: it adds travel time to every pick cycle, creates congestion at zone boundaries and restricts throughput at the moments of highest operational pressure.
Each zone carries specific design requirements:
- Receiving: sized to accommodate peak inbound volumes with adequate staging area for quality checking, labelling and put-away. Positioned to provide direct access to bulk storage without crossing active pick face aisles.
- Bulk storage: configured for density and FIFO rotation, with a direct replenishment flow into the pick face that does not disrupt active picking operations.
- Pick face: the highest-activity zone in any FMCG facility, configured for speed, accuracy and FIFO compliance. Pick face depth, aisle width and slot allocation all affect pick rate directly and must be designed together rather than independently.
- Dispatch: positioned to minimise travel distance from the pick face, with staging capacity for full order consolidation before loading.
Zone sizing must account for peak volume, not average throughput. A layout that performs efficiently at average volume but cannot handle seasonal peaks will consistently underperform at the moments when performance matters most.
Racking systems for FMCG environments
No single racking system suits every FMCG application. A high-volume distribution centre typically uses a combination of systems, each matched to a specific velocity band, SKU profile and FIFO requirement. The four systems that most commonly appear in FMCG warehouse design are drive in or shuttle racking for bulk single-SKU lines, carton live storage for pick face FIFO compliance, selective pallet racking for medium-velocity lines and double deep racking where density is the priority and selectivity can be partially managed. Each is covered below with its application context and trade-offs.
Drive-in racking for bulk storage
Drive-in racking is a high-density bulk storage system in which forklifts travel into the racking lane to load and retrieve pallets. Standard drive-in racking operates on a last-in, first-out basis because pallets are loaded and retrieved from the same end of the lane. For FMCG operations carrying short-dated inventory, this creates a direct FIFO compliance problem that must be addressed at the design stage.
Shuttle racking offers a semi-automated alternative that resolves the FIFO limitation of conventional drive-in systems. A motorised shuttle carries pallets along the depth of each lane, allowing loading from one end and retrieval from the other to support first-in, first-out rotation. This combines the high-density footprint of drive-in racking with the stock rotation discipline FMCG distributors require for dated goods, while also reducing forklift travel inside the lane and lowering the risk of impact damage to the structure.
Carton live storage for pick face FIFO compliance
Carton live storage, also known as flow racking, is a gravity-fed shelving system in which stock loads from the rear of the lane and moves forward on roller tracks to the pick face. The oldest carton reaches the front of the lane first, delivering automatic first-in, first-out rotation without operator intervention or reliance on pick sequence discipline.
This makes carton live storage the most reliable FIFO solution for high-velocity, short-dated pick face lines in FMCG distribution. It suits products picked by the carton or unit from a high-SKU pick face, including ambient grocery, beverage, personal care and household goods lines where date rotation is a compliance and quality requirement.
Replenishment happens from the rear of the system, which means pick and replenishment activities occur simultaneously without interrupting each other. This separation of pick and replenishment flows is a significant throughput advantage in high-volume FMCG operations where pick face downtime directly affects order fulfilment rates and customer service levels.
Pallet racking for medium-velocity lines
Selective pallet racking systems provide direct access to every pallet position without requiring other pallets to be moved, making them the most flexible storage system for medium-velocity FMCG lines with multiple SKUs per bay. Where a distribution centre carries a wide product range with uneven velocity profiles, pallet racking allows the layout to accommodate slow-moving and medium-moving lines alongside each other without the lane-commitment constraint of drive-through systems.
FIFO rotation in selective pallet racking depends on operator discipline and bay labelling rather than system configuration. For short-dated products stored in selective racking, a clear labelling system and a documented put-away sequence are necessary controls. For high-velocity or consistently short-dated lines, carton live storage or drive-through racking provides more reliable FIFO enforcement without relying on individual operator compliance to maintain date rotation accuracy.
Double deep racking as a density option
Double deep racking stores pallets two positions deep in a single bay, increasing storage density by reducing the number of aisles required compared to selective pallet racking. For FMCG operations with high-volume single-SKU lines that require more density than selective racking provides but do not justify full drive-through lane configuration, double deep racking offers a practical middle-ground solution.
The trade-off is selectivity. Accessing the rear pallet requires the front pallet to be moved first, which limits double deep racking to applications where both positions in a bay hold the same SKU and FIFO rotation is managed through a disciplined put-away sequence. For FMCG lines where date rotation is critical and lane discipline cannot be guaranteed, carton live storage or drive-through racking remains the lower-risk option. Storepro’s double deep racking page covers configuration and installation specifications for NZ distribution operations.
Aisle configuration and pick rate trade-offs
Aisle width is one of the most consequential layout decisions in an FMCG distribution centre because it directly determines the balance between storage density and pick rate. Wider aisles allow faster forklift movement and higher pick throughput but reduce the number of racking bays that fit within a given footprint. Narrower aisles increase storage density but require specialised equipment at higher procurement and maintenance cost.
| Aisle type | Typical width | Equipment required | Storage density | Pick rate | Best-fit application |
| Wide aisle | 3,500 mm or more | Counterbalance forklift | Lower | High | Bulk storage, receiving and dispatch zones |
| Narrow aisle | 2,500–3,000 mm | Reach truck | Medium | Medium-high | Mixed-velocity pick face and bulk storage |
| Very narrow aisle | 1,600–2,000 mm | Turret truck or order picker or Articulated machine | High | Lower | High-density pick face in space-constrained facilities |
Most high-volume FMCG distribution centres use a combination of aisle widths across different zones rather than a single configuration throughout. The right configuration depends on the ratio of bulk storage to pick face, the equipment fleet in use and whether throughput velocity or storage density is the binding operational constraint in each zone.
Vertical space: mezzanine floors in FMCG facilities
Mezzanine floors extend usable area upward within an existing building footprint, making them a practical capacity option for FMCG facilities operating in space-constrained sites where expanding the footprint is not viable. In FMCG distribution environments, mezzanine floors typically serve functions that benefit from physical separation from the main warehouse floor: pick face overflow for slow-moving lines, returns processing, packing operations and value-added services. AGV and AMR can be utilised on a structural mezzanine structure.
Building consent is required for most mezzanine floor installations in New Zealand under the Building Act 2004, and fire safety requirements including egress, sprinkler systems and emergency lighting apply. These requirements affect both the design timeline and total project cost and must be factored into fit-out planning from the initial design stage, not added as a late-stage compliance task.
For operations considering mezzanine floors as part of a broader FMCG warehouse fit-out, Storepro designs and installs raised storage areas and mezzanine floors to NZ compliance standards as part of an integrated warehouse design and fit-out service.
FIFO compliance by design
FIFO compliance that depends on operator behaviour is a failure mode in high-volume FMCG distribution. When pick sequence discipline is the primary control for date rotation, the risk of non-compliance increases with pick face volume, staff turnover and time pressure. A warehouse design that enforces FIFO at the system level removes this dependency.
System-level FIFO enforcement operates through three mechanisms. Racking configuration determines whether the oldest product physically reaches the pick face first: carton live storage and drive-through racking deliver this automatically through their physical design. Bay and slot labelling systems direct put-away and replenishment to the correct position without requiring the operator to make a rotation decision. Pick sequencing in warehouse management systems assigns picks in date order where selective racking is used and automatic rotation is not possible.
The most reliable FIFO systems in FMCG distribution combine physical enforcement through racking configuration with labelling and system-directed sequencing as a secondary control layer. Treating operator discipline as the primary line of defence against date rotation failure is not consistent with the spoilage and compliance risk profile that FMCG products carry.
Designing for peak volume and seasonal flexibility
FMCG distribution centres face predictable volume peaks (Christmas, Easter and promotional periods) that place acute pressure on every zone in the facility. A layout optimised for average throughput but not for peak demand creates a recurring operational problem at the moments when customer expectations are highest and the cost of failure is greatest.
Strategies for accommodating seasonal volume without over-capitalising on permanent footprint include:
- Modular racking: specify systems that can be extended or reconfigured quickly as temporary capacity is needed, without structural modification to the building.
- Temporary storage zones: identify floor areas adjacent to receiving and dispatch that can be activated as additional staging during peak periods without disrupting normal pick face operations.
- Aisle width for peak equipment: design aisle widths to accommodate peak equipment density, not just the standard operating fleet, particularly where additional forklifts are deployed during high-volume periods.
- Buffer zone sizing: size receiving and dispatch staging areas for peak inbound and outbound volumes, not average daily throughput.
