NZ Post Prepaid Bags: Sizes, Prices & Bundles 2024
NZ Post has quietly retired its old multi-range prepaid bag system and replaced it with a single unified line.

How much do NZ Post bags cost?
Single bag prices
NZ Post now sells bags individually at a fixed rate, then you choose which service ticket to add. Courier service costs $2.00 more than Economy across every size, making the trade-off straightforward: pay the premium for next-day urban delivery, or save by accepting 2–3 working days. Single bags range from $1.00 for standard XS through M up to $8.00 for the XXL, with Bubble variants priced $1–3 higher for extra protection.
| Size | Dimensions (mm) | Bag Only | Courier + Bag | Economy + Bag |
|---|---|---|---|---|
| XS | 240 × 130 | $1.00 | $8.40 | $6.40 |
| S | 280 × 190 | $1.00 | $9.70 | $7.70 |
| S Bubble | 280 × 190 | $2.00 | $10.70 | $8.70 |
| M | 325 × 255 | $1.00 | $11.80 | $9.80 |
| L | 380 × 280 | $1.00 | $12.80 | $10.80 |
| L Bubble | 380 × 300 | $3.00 | $14.80 | $12.80 |
| XL | 400 × 440 | $2.00 | $18.00 | $16.00 |
| XXL | 750 × 515 | $8.00 | Counter price | Counter price |
Bundle prices
For anyone sending more than a few parcels a month, the bundle model is where the real value lies. Each bundle includes 20 bags plus 20 matching service tickets, sold as a single unit. The per-bag cost in bundles drops noticeably compared to buying bags and tickets separately. Courier bundles range from $168 for XS up to $360 for XL, while Economy bundles save $40 per set across every size. A small online seller moving 20 parcels monthly would pay $8.40 per send via individual purchase, or roughly $8.40 all-in via bundle — but the bundle eliminates per-transaction effort and ensures tickets are always to hand.
| Size | Dimensions (mm) | Courier Bundle (20 units) | Economy Bundle (20 units) |
|---|---|---|---|
| XS | 135 × 240 | $168.00 | $128.00 |
| S | 190 × 280 | $194.00 | $154.00 |
| M | 257 × 325 | $236.00 | $196.00 |
| L | 280 × 380 | $256.00 | $216.00 |
| XL | 400 × 440 | $360.00 | $320.00 |
For high-volume senders, pre-buying a bundle before the July 2025 rate change is worth running the numbers on. The XS Courier bundle works out to $8.40 per send — the same as buying components separately — but bundles lock in the ticket-to-bag pairing and skip a trip to the Postshop each time.
The pattern is consistent: Courier costs $2.00 more than Economy at every size, and bubble bags add a flat $1–3 premium over standard. NZ Post has confirmed that bag pricing will not change with the 1 July 2025 parcel rate adjustment, though the services themselves will rise an average 2.8% (NZ Post Official).
What sizes are available for NZ Post prepaid bags?
XS dimensions
The XS is NZ Post’s smallest prepaid bag at 240mm × 130mm. It’s designed for jewellery, small electronics, or documents — items that fit within a rigid flat envelope. Third-party packaging suppliers note this size works for small tech accessories and lightweight jewellery pieces (Primepac Industrial Blog). All bags carry a maximum weight limit of 3kg, regardless of size.
- XS: 240mm × 130mm — smallest, for jewellery and tech
- S: 280mm × 190mm — clothing, small goods
- M: 325mm × 255mm — medium parcels, multiple items
- L: 380mm × 280mm — lightweight larger items
- XL: 400mm × 440mm — largest standard size
- XXL: 750mm × 515mm — oversized, counter pricing only
S, M, L, XL options
Each size up from XS adds roughly 50–60mm in each dimension, creating a clear progression for progressively larger items. The S and M sizes offer Bubble variants at $1–2 extra — those are the ones to reach for when your item includes glass, ceramics, or anything fragile. NZ Post officially lists dimensions as consistent across sources for S, M, L, and XL, with minor notation variations (NZ Post Official). The L Bubble bag measures 380mm × 300mm — the extra depth compared to the standard L accommodates cushioning for fragile contents.
The XL bag sits at 400mm × 440mm with a $2.00 bag-only price and $18.00 Courier total. Its 20-unit Courier bundle is $360 — more than double the XS bundle cost. If you’re regularly shipping XL parcels, the per-send math with an XL bundle ($18.00 each) nearly matches individual purchase pricing, so the bundle’s value is mainly convenience, not saving.
All bags in the range are made from 80% recycled plastic, which is worth noting for businesses with sustainability commitments or customers who ask. NZ Post’s official product pages confirm this material composition across the single bag range (NZ Post Official).
Where can I buy NZ Post prepaid bags?
Online shop
The NZ Post online shop is the primary outlet for bundle purchases. Bundles of 20 bags plus matching tickets are available exclusively online, with individual bags also listed at their standard retail price. The shop lists bundles by service type (Courier or Economy) and size, making it straightforward to find the right combination (NZ Post Official Shop).
Post offices
Physical Postshops carry individual bags for immediate purchase without waiting for delivery. The standard range from XS to XL is reportedly available at most locations, though stock of larger sizes may vary. Single XXL bags require counter pricing and are not stocked as a standard prepaid item.
- Bundles: online shop only (20 bags + 20 tickets per unit)
- Individual bags: Postshops nationwide, or online for single purchases
- XXL bags: counter pricing at Postshops — not sold as prepaid
Single vs packs
The shift to bundles changed how many New Zealanders buy these products. Previously, smaller packs of 5 or 10 bags were common; now the minimum online bundle is 20 units. This matters most for occasional senders — someone mailing a handful of parcels yearly may find individual bags at their local Postshop more practical than committing to a 20-unit bundle. For regular senders, however, the bundle model reduces per-transaction friction and ensures stamps are always available.
If you send fewer than 10 parcels a month, buying individual bags at Postshops avoids tying up capital in a 20-unit bundle. The per-bag cost is the same either way — the bundle’s advantage is convenience, not a discount.
Do NZ Post prepaid bags expire?
Pre-2023 bags
NZ Post has confirmed that bags purchased before 1 July 2023 — the ones that had service pricing printed directly on the bag — remain valid for sending (NZ Post Official). The change that July was to new sales format, not a recall or expiry of existing stock. If you have older bags sitting in a drawer, they’re still usable with no deadline. The old bags work fine alongside the new range.
Current bags
The new single bag range intentionally omits printed pricing — instead, the bag is one component and the ticket is purchased separately. This means the bags themselves don’t carry a service-specific expiry, but they also can’t be used alone. The ticket you buy separately determines the service level and validity window. For domestic sending, all current bags carry a consistent 3kg maximum weight limit and are domestic-use only.
- Pre-2023 bags: still usable, no expiry
- Current bags: no printed pricing, require separate ticket
- All bags: domestic NZ only, max 3kg
What are NZ Post bag and ticket bundles?
Courier bundles
The Bag + Courier Ticket bundle pairs 20 prepaid bags with 20 matching CourierPost tickets — the next-day service for domestic parcels. The bundle cost includes GST and covers the full send: bag plus ticket. Sizes run XS through XL, with prices from $168 (XS) to $360 (XL) (NZ Post Official – Bag Bundles). Each bundle ships as a single unit, and the per-send cost works out to $8.40 for XS, $9.70 for S, $11.80 for M, $12.80 for L, and $18.00 for XL.
Economy options
Economy bundles use the same bag sizes but pair with the slower, cheaper service — 2–3 working days instead of next-day. The saving is $40 per bundle across every size, which translates to $2.00 per send. For non-urgent parcels, the Economy bundle is the sensible choice. The bag and ticket are physically identical between the two service tiers; only the ticket colour and tracking level differ.
- Courier bundles: next-day urban delivery, $168–$360 for 20 units
- Economy bundles: 2–3 working days, $40 less per set
- All bundles: bags made from 80% recycled plastic, max 3kg per bag
For a Christchurch business shipping regular parcels to Auckland, the Economy bundle’s $2.00 per-send saving adds up fast — 100 parcels a month is $200 saved versus Courier. Unless delivery speed genuinely matters to customers, Economy bundles represent better margin management.
Timeline of key changes
Understanding the context of when things changed helps explain why the product range looks the way it does today.
| Date | Change |
|---|---|
| Before 1 July 2023 | Prepaid bags sold with service pricing printed directly on the bag; multiple bag ranges in circulation |
| 1 July 2023 | NZ Post simplified to a single bag range for all sending needs; bundles introduced; bags no longer printed with specific pricing |
| 1 July 2024 | Domestic small parcel services increased average 2.8%; bag pricing remained stable; standard mail and KiwiStamp prices updated |
| 1 July 2025 | Next domestic small parcel rate review; bag-only pricing confirmed unchanged; Rural Surcharge confirmed stable |
The direction is consistent: NZ Post is simplifying its prepaid offering while keeping the service tiers intact. Bags and tickets are now separate components, but bundles re-combine them for practical convenience. The July 2024 Q&A document from NZ Post notes that prepaid product price increases reflect the additional costs associated with handling and delivering these items through their automated network (NZ Post Official).

Frequently asked questions
Can I use old NZ Post prepaid bags after 2023?
Yes. NZ Post has confirmed that bags purchased before 1 July 2023 remain valid for sending. The change that July affected new sales format, not existing stock. Your older bags with printed pricing still work — there’s no expiry date.
Are NZ Post prepaid bags only for domestic mail?
Yes. All NZ Post prepaid bags are designed for domestic New Zealand sending only. International parcels require different packaging and service options. The bags and tickets are not valid for overseas destinations.
What payment methods for NZ Post bag bundles?
Bundles purchased through the NZ Post online shop accept standard online payment methods including credit and debit cards. For Postshop purchases of individual bags, payment options follow the standard retail point-of-sale rules at each location.
How do I track a parcel in a NZ Post prepaid bag?
Tracking depends on the service ticket. Courier tickets include full tracking with signature and delivery confirmation. Economy tickets include basic tracking with fewer scan points. Bag-only purchases without a ticket do not include any tracking capability — you need the service ticket for that.
Is there a minimum order for NZ Post bags?
There is no stated minimum order for individual bags. Bundle purchases through the online shop are sold as 20-unit sets. For bulk commercial orders, NZ Post offers business account options with different pricing structures — worth exploring if you send more than 50 parcels monthly.
What if my item doesn’t fit NZ Post bag sizes?
For items too large for the XXL bag (750mm × 515mm), NZ Post offers boxes and other packaging options at the online shop and Postshops. Fragile or irregular-shaped items may be better served by double-wall boxes rather than bags. The Rate Finder tool on the NZ Post website can help match your item dimensions to the right packaging choice.
Are NZ Post bags waterproof?
Standard NZ Post prepaid bags are not explicitly marketed as waterproof. The Bubble variants offer more protection against moisture and impacts, but for items sensitive to water damage, adding a sealed plastic liner or choosing box packaging is recommended, especially during wet weather or for coastal/rural deliveries.
