A fully automated fill-and-seal tub line — built for brands scaling out of hand-fill production.

Line status: The Whenuapai tub line is coming online — contact us about timing for your run and to reserve capacity.

What's included

  • Fully automated fill-and-seal line
  • Estimated throughput: up to 20 tubs/min on 6.8 L containers (validated example — not a universal rate)
  • Other tub sizes and formats confirmed during line validation
  • Consistent fill weights to label claim at volume

Applications

Protein powders, greens blends, pre-workout, electrolytes and meal replacements in retail tub formats.

Minimum order quantity

Pilot batches available

Small development batches are available before committing to commercial runs. MOQ for commercial production is discussed as part of your quote and depends on format and formulation. Request a quote to get a specific range.

Lead times

Indicative timeframes

Development batches are scheduled from approved formulation; commercial production follows batch sign-off, plus ingredient lead time. Exact timeframes are confirmed at quoting stage. Tub runs at our Whenuapai line: now taking bookings — talk to us to confirm your slot and get an indicative go-live window. Request a quote for a specific timeframe.

Ideal use cases

The line is built for powder products sold in retail tubs — protein, greens, pre-workout, electrolytes and meal replacements. The brand profile it suits best: you're hand-filling hundreds of tubs a run, and it's breaking — your time, your consistency, or both.

  • Powder brands outgrowing hand-fill or semi-manual filling
  • Consistent fill weights to label claim, run after run
  • Retail-ready output — filled and sealed in one automated pass

Changeover & tub specification

These are the things we confirm with you at quoting — not fixed constraints, but the questions that decide how your product runs:

Confirmed as part of your quote
Tub dimensions
Container size and shape — validated per format before your run
Lid & seal type
Seal and closure compatibility confirmed at line validation
Fill weight & run length
Target fill vs label claim, and changeover planning between products

Bring your tub spec — we'll confirm compatibility and changeover approach as part of your quote. Request a quote.

Where your product is made

Tub runs use both of our Auckland sites, and we're explicit about which credentials attach to which — because accurate certification claims are exactly what you should expect from a manufacturer.

Common questions about tub filling.

When is the tub line live?

The Whenuapai line is coming online now — we are taking capacity reservations for early runs. Talk to us about timing for your product and we will confirm an indicative go-live window as part of your quote.

What tub sizes can you run?

Estimated throughput is up to 20 tubs per minute on 6.8-litre containers — an estimated example, not a universal rate. Other tub sizes and formats are confirmed during line validation for your specific container, so bring your tub spec to the quote.

Is the Whenuapai site GMP-certified?

No — our GMP-NZ certification (SGS, NZ25/00000030) covers the Rosedale facility, where blending and quality release happen. Automated tub filling runs at Whenuapai. We keep that distinction explicit because accurate certification claims are exactly what you should expect from a manufacturer.

Can you blend and fill in one engagement?

Yes — most tub clients do exactly that. Your powder is blended under GMP-NZ process control at Rosedale, then filled and sealed on the automated line at Whenuapai, with batch documentation covering the full run.
