Carry-on luggage is any bag or case sized to fit in an aircraft cabin’s overhead locker or under the seat, rather than being checked into the hold. Air New Zealand’s standard cabin allowance is 118cm total dimensions and 7kg, though this varies by airline and fare class.
Carry-on comes in a few distinct forms. Hard-shell cases use a rigid ABS or polycarbonate shell for impact protection. Soft-sided cases and duffels compress into tight spaces and are generally lighter. Luggage sets bundle a carry-on with one or more larger checked-size pieces. Front-opening cases add a separate zippered pocket for quick access to a laptop or documents.
Weight matters as much as size: since most airlines cap cabin bags at 7 to 9kg including the bag itself, a lighter empty case (2 to 3kg) leaves more of that allowance for what you actually pack.
This guide compares hard-shell, soft-sided and multi-piece carry-on options available in New Zealand, across a range of budgets and weights.

1. 2-Piece Luggage Set – Best Value Carry-On Set
This set pairs a genuine 20-inch carry-on (36 x 23 x 57cm, 2.7kg) with a larger 28-inch checked piece, so the carry-on itself is the pick here rather than needing to buy a standalone case.
An aluminium pull rod, TSA-approved combination lock and smooth 360-degree dual spinner wheels cover the core features expected of any decent carry-on, and the 20-inch piece nests inside the 28-inch piece for compact storage between trips.
At 2.7kg empty, the carry-on piece itself is genuinely light, leaving more of the airline’s weight allowance for what you actually pack.
Pros
- The 20-inch carry-on piece alone weighs a light 2.7kg empty
- TSA-approved lock and 360° spinner wheels cover the essentials
- Nests inside the larger 28-inch piece for compact storage
Cons
- Sold as a 2-piece set, so you’re paying for a checked-size piece even if you only need the carry-on
- Stock on this specific listing has been running low
Key specs: Carry-on size: 20″ (36 x 23 x 57cm). Carry-on weight: 2.7kg. Carry-on capacity: 40L. Lock: TSA-approved.
2. 4-Piece Luggage Set (16″/20″ Carry-On/24″/28″) – Best Multi-Size Family Set
This set includes a genuine 20-inch carry-on alongside a 16-inch mini trolley, a 24-inch medium spinner and a 28-inch large suitcase, covering a family’s full range of trip lengths from one purchase.
Corner guard protectors add extra impact protection over a plain hard shell, and TSA-approved locks on the two larger pieces plus combination locks on the two smaller pieces cover security across the whole set.
All three smaller pieces pack inside the 28-inch suitcase for storage, and six packing cubes plus a protective cover are included as a bonus rather than sold separately.
Pros
- Genuine 20-inch carry-on included alongside 3 other useful sizes
- Corner guard protectors add extra impact protection over a plain shell
- Includes 6 packing cubes and a protective cover as a bonus
Cons
- A 4-piece set is more than most people need if they only travel with a carry-on
- Larger overall purchase than the 2-piece set if storage space is limited
Key specs: Carry-on size: 20″ (34.5 x 22 x 55cm approx.). Set includes: 16″, 20″, 24″, 28″. Extras: 6 packing cubes, protective cover.
3. TSB 2-Piece PC & Aluminium Luggage Set – Best Carry-On + Checked TSB Set
This TSB set steps up the build quality with a polycarbonate and ABS shell reinforced by a genuine aluminium frame and corner guards, rather than a plain hard shell alone.
The 20-inch carry-on piece carries a 10kg capacity at just 3.09kg net weight, and dual TSA lock buckles plus 360-degree silent spinner wheels round out a set built for regular business or holiday travel.
A spacious interior with mesh pockets helps keep smaller items organised, and protective PVC covers are included to keep both pieces looking new between trips.
Pros
- Polycarbonate shell with an aluminium frame is more robust than a plain ABS shell
- Dual TSA lock buckles on a set built for regular travel
- Protective PVC covers included to keep both pieces looking new
Cons
- Costs more than the equivalent bestdeals sets in this guide
- Aluminium frame adds a small amount of weight over a frameless design
Key specs: Carry-on size: 20″ (40 x 23 x 57.8cm). Carry-on weight: 3.09kg. Carry-on capacity: 10kg load. Set includes: 20″, 28″.
4. TSB 3-Piece Front Open Luggage Set – Best Front-Opening Carry-On
Unlike a standard top-loading case, this set’s front-opening design gives quick access to your essentials without needing to lay the whole case flat and unzip it fully, similar in spirit to a laptop bag’s front pocket.
The 20-inch carry-on piece carries a 10kg capacity, and an expandable zip on top of the front-opening design adds extra packing room when needed for a longer trip.
An aluminium telescopic handle and 360-degree double spinner wheels round out a set that also includes 24-inch and 28-inch pieces for longer trips or checked luggage.
Pros
- Front-opening design gives quick access to essentials without fully unpacking
- Expandable zip adds extra packing space on top of the front-access feature
- Includes 3 genuinely different sizes (20″, 24″, 28″) for varying trip lengths
Cons
- Front-opening design has more zippers and moving parts than a simple top-loader
- 3-piece set costs more upfront than a single carry-on case
Key specs: Carry-on size: 20″ (34.5 x 22 x 55cm). Carry-on capacity: 10kg. Set includes: 20″, 24″, 28″. Lock: TSA.
5. TSB Expandable Foldable Duffel Bag Suitcase – Best Soft-Sided Hybrid Carry-On
Rather than a rigid hard shell, this is a soft-sided duffel bag with 4 removable wheels, letting it switch between a rolling case and a carry-by-hand duffel depending on what a trip needs.
At just 1.15kg and folding down to a flat 32 x 52 x 5cm, it’s the most packable option in this guide, worth keeping as a spare bag for a trip home with extra souvenirs.
Its compact 40 x 22 x 42cm size suits a short trip or as a personal item alongside a larger case, rather than being sized as a primary week-long carry-on.
Pros
- Switches between a rolling case and a hand-carried duffel via removable wheels
- Folds flat to 32 x 52 x 5cm, the most packable option in this guide
- At 1.15kg it’s genuinely light for a spare or secondary bag
Cons
- Smaller than a standard 20-inch carry-on, better as a secondary bag than a primary one
- Soft sides offer less impact protection than any hard-shell case in this guide
Key specs: Size: 40 x 22 x 42cm. Weight: 1.15kg. Wheels: 4, removable. Folded size: 32 x 52 x 5cm.
6. Samsonite Oc2lite 55cm – Best Overall
Samsonite’s Oc2lite is the #1 best-selling suitcase on Amazon AU, and at 55cm it’s sized as a standard airline carry-on with a genuine brand reputation behind it rather than a generic import.
An expandable design adds extra packing space when needed, and functional elastic cross ribbons inside help keep packed items from shifting during transit.
A 3-digit integrated TSA combination lock, 360-degree multidirectional spinner wheels and anti-theft zips round out a well-specified, widely-trusted carry-on.
Pros
- #1 best-selling suitcase on Amazon AU with a large, genuine review base
- Expandable design adds packing space when needed
- Anti-theft zips add peace of mind travelling through busy airports
Cons
- Costs more than the budget picks in this guide for a single case
- Available in fewer colour options than some competitors
Key specs: Size: 55cm (standard carry-on). Lock: 3-digit integrated TSA. Wheels: 360° multidirectional spinner. Design: expandable.
7. Amazon Basics Hardside Expandable Spinner 55cm – Best Budget Carry-On
With over 26,000 reviews, this is one of the most-reviewed carry-on suitcases on Amazon AU, and its price sits well below the branded picks in this guide without dropping the core features.
A protective, scratch-resistant ABS hard shell and 4 double spinner wheels cover the essentials, and a sturdy telescoping handle keeps it comfortable to wheel through a busy airport.
Sold individually or as part of a 2-piece or 3-piece set alongside larger checked sizes, it’s flexible for anyone who might want to add a matching larger case later.
Pros
- Over 26,000 reviews make it one of the most-proven carry-ons on Amazon AU
- Scratch-resistant ABS shell at a genuinely budget price
- Available individually or bundled with larger matching sizes
Cons
- Fewer premium features (no aluminium frame, no front pocket) than the pricier picks in this guide
- Amazon Basics is the product’s own brand, not a dedicated luggage specialist
Key specs: Size: 55cm carry-on. Shell: ABS hard shell. Wheels: 4 double spinner wheels. Options: sold individually or as a 2/3-piece set.
8. CENSIEN Expandable 20″ with Front Laptop Pocket – Best for Business Travel
Where most carry-ons need to be fully opened to reach anything inside, this CENSIEN case has a dedicated front pocket with a laptop compartment, letting you grab a laptop or documents at security without unpacking.
A 20% expandable design adds packing space for longer trips, and the 41.5L capacity at 20 inches is sized to comply with most airlines’ carry-on regulations, though allowances do vary by airline.
YKK zippers, a TSA lock and 360-degree spinner wheels round out a case clearly aimed at frequent business travellers rather than occasional holidaymakers.
Pros
- Front pocket with a dedicated laptop compartment for quick access at security
- 20% expandable design adds packing space for longer trips
- YKK zippers are a genuine step up from generic zipper hardware
Cons
- The front pocket adds bulk compared with a simple single-compartment case
- 41.5L capacity means checking your specific airline’s allowance before flying
Key specs: Size: 20″ (41.5L capacity). Extras: front pocket with laptop compartment. Zippers: YKK. Lock: TSA.
9. Bellroy Lite Carry-On 38L – Best Premium Soft-Sided Carry-On
Bellroy’s Lite Carry-On trades a hard shell for a compressible ripstop nylon shell, squishing into tight overhead spaces that a rigid case can’t, while still keeping structure through built-in packing cells.
At just 2.1kg, it’s noticeably lighter than every hard-shell pick in this guide, leaving more of the airline’s weight allowance for what’s actually packed inside.
Rollerblade-inspired wheels and a custom telescopic handle with 3 lockable heights are self-replaceable, and the whole bag is backed by a 10-year warranty from a brand with a strong reputation for durability.
Pros
- At 2.1kg it’s the lightest carry-on in this guide by a clear margin
- Compressible shell squeezes into tight overhead spaces a hard shell can’t
- 10-year warranty reflects real confidence in long-term durability
Cons
- The most expensive pick in this guide
- Soft sides offer less impact protection than the hard-shell picks
Key specs: Volume: 38L. Weight: 2.1kg. Size: 510 x 345 x 230mm. Warranty: 10 years.
How to Choose Carry-On Luggage
Check your airline’s actual limits. Size limits catch fewer travellers out than weight limits do; weigh your packed bag before flying, since a 7kg cabin allowance includes the case itself.
Hard shell vs soft sided. A hard shell protects fragile items better; a soft-sided or compressible case is generally lighter and squeezes into tighter overhead spaces when a flight is full.
Buying a set vs a single case. A multi-piece set is worth it if you’ll genuinely use the larger checked pieces; if you only ever travel with a carry-on, a single case avoids paying for sizes you won’t use.
Extra features. A front-access pocket suits frequent business travel where you need a laptop out quickly; expandable zips add packing space for the trip home when you’ve bought souvenirs.
If you’re deciding between carry-on and checked luggage more broadly, our guide to suitcases covers larger checked-size options.
Verdict
For most travellers, the Samsonite Oc2lite is the strongest all-round pick: a genuinely trusted brand, a large proven review base, and solid features at a reasonable price. If budget is the priority, the Amazon Basics Hardside is nearly as well-proven for a lower cost, and the bestdeals and TSB sets are worth it specifically if you’ll use the larger checked pieces too, not just the carry-on. Business travellers should look at the CENSIEN for its front laptop pocket, and anyone prioritising low weight over hard-shell protection should consider the Bellroy Lite Carry-On or the TSB foldable duffel as a lighter alternative.
Frequently Asked Questions
What is the carry-on size for Air New Zealand?
Air New Zealand’s standard cabin bag allowance is 118cm total dimensions with a 7kg weight limit for most domestic and short-haul international flights, though this can vary for long-haul flights and by fare class. Always check your specific fare’s allowance before flying.
What is the max weight for carry-on luggage?
Most airlines cap carry-on weight between 7kg and 9kg, including the weight of the empty bag itself. A lighter empty case leaves more of that allowance for what you actually pack.
What is the best size for carry-on luggage?
A 20-inch or 55cm case is the most widely accepted carry-on size across airlines, though some budget carriers have stricter limits. Check your specific airline’s dimensions, which commonly sit around 56 x 36 x 23cm, before buying.
Should I buy a single carry-on or a multi-piece luggage set?
A single case avoids paying for checked-size pieces you won’t use if you only ever travel with carry-on. A multi-piece set is better value if you’ll genuinely use the larger pieces for longer trips or checked baggage.
Is a hard-shell or soft-sided carry-on better?
A hard shell offers better protection for fragile items and a cleaner look, while a soft-sided or compressible case is generally lighter and can squeeze into a tight overhead locker when a flight is full.
How do I stop my carry-on getting damaged in transit?
Even carry-on bags occasionally get gate-checked on full flights, so look for corner guard protectors on a hard-shell case, and avoid overpacking soft-sided bags past their rated capacity, which puts extra strain on zippers and seams.
