Few packing questions spark as much last-minute scrambling as what you can and can’t put in your checked bag. If you’re flying from New Zealand and wondering whether that can of deodorant or hairspray belongs in your suitcase or your carry-on, the answer isn’t always the same. New Zealand’s Civil Aviation Authority (CAA) sets specific limits on aerosols in checked baggage, and Air New Zealand follows those rules closely — but domestic flights within the country play by a different set of rules altogether.

Can I pack an aerosol in my checked luggage?

General rules for aerosols in checked baggage

  • Aerosols are allowed in checked baggage with restrictions — each container must not exceed 500ml (500g) per New Zealand Civil Aviation Authority (aviation regulator).
  • Personal aerosols like deodorant and hairspray are permitted — Air New Zealand (national airline).
  • Non-flammable aerosols are allowed; some industrial aerosols may be prohibited — CAA (aviation regulator).

What types of aerosols are allowed?

  • Toiletry aerosols (deodorant, hairspray, shaving cream) are all fine.
  • Medicinal aerosols (asthma inhalers, topical sprays) are permitted — declare them at security if unsure.
  • Insect repellent and sunscreen aerosols are allowed as long as they comply with the 500ml limit — SCTI NZ (travel insurance provider).
The upshot

Most travellers can safely pack their everyday aerosols in checked luggage without drama. The catch: containers that exceed 500ml, or those marked with flammable warnings, will be removed at the airport.

The implication: for anyone flying domestically within New Zealand, none of these rules apply — you can pack your full-size can of deodorant without a second thought.

Can you take aerosols in checked baggage with Air NZ?

Air New Zealand policy on aerosols

Air NZ checked baggage prohibited items

  • Aerosols that are not medicinal or toiletry items are restricted — Air New Zealand (national airline).
  • Battery-powered wheelchairs or mobility devices may only be carried as checked-in baggage and must be declared when booking — Air New Zealand (national airline).
  • Alcohol may be carried in both checked-in bags and carry-on, subject to alcohol-strength and volume limits — Air New Zealand (national airline).
What to watch

Air New Zealand’s policy mirrors the CAA’s — no surprises there. The real trap for travellers is assuming the same rules apply to domestic flights. They don’t.

The pattern: International carry-on restrictions don’t affect domestic travel within New Zealand at all.

Is there a limit on aerosols in checked baggage?

Maximum size per container

  • Each aerosol container must not exceed 500ml (500g) in checked baggage — Civil Aviation Authority of New Zealand (aviation regulator).
  • For carry-on, the limit is 100ml per container — CAA (aviation regulator).
  • If a container lists both millilitres and grams, millilitres must be used to measure the container size — CAA (aviation regulator).

Total volume limits for aerosols

  • No specific total volume limit stated by NZ CAA for checked baggage.
  • For carry-on, total liquids-aerosols-gels cannot exceed 1 litre — CAA (aviation regulator).
  • Jetstar requires that the bag holding liquids-aerosols-gels must have a sealed area of no more than 80 cm², such as 20 x 20 cm — Jetstar (airline policy).
The CAA’s stance: The CAA does not set a total quantity cap on aerosols in checked baggage — only a per-container limit of 500ml. For carry-on, the 100ml rule is strict and the total bag can hold no more than 1 litre. Domestic flyers in New Zealand can ignore these limits entirely.

Do aerosols go in hand luggage or suitcase?

When to use carry-on vs checked baggage

  • Aerosols under 100ml can go in carry-on — CAA (aviation regulator).
  • Aerosols over 100ml must go in checked baggage — CAA (aviation regulator).
  • International carry-on passengers may take no more than one litre of liquids, aerosols and gels in total — CAA (aviation regulator).

Packing aerosols for domestic flights

  • Domestic flights within NZ have no aerosol restrictions — Aerosol Industry Council NZ (industry body).
  • Air New Zealand confirms PLAG restrictions do not apply to domestic flights within New Zealand — Air New Zealand (national airline).
  • Jetstar says liquids-aerosols-gels for domestic flights departing from an international terminal must still be in containers of 100ml or less — Jetstar (airline policy).
The catch

If your domestic flight departs from an international terminal (common at Auckland Airport for flights to the Cook Islands, Niue, or the Chatham Islands), the international carry-on rules still apply. Always check the terminal you’re flying from before packing.

The implication: most travellers should default to putting large aerosols in checked luggage. If you’re flying domestically and not going through international security, you have full flexibility. For international travel, the only choice is between carry-on (under 100ml) and checked (under 500ml).

What happens if you put an aerosol in checked luggage?

Security screening outcomes

  • If an aerosol is prohibited, it may be confiscated at security — CAA (aviation regulator).
  • Aerosols that comply with size limits will pass screening — CAA (aviation regulator).
  • Damaged or leaking aerosols may be removed — SCTI NZ (travel insurance provider).

Confiscation and penalties

  • Prohibited items found in checked baggage are removed; the traveller may not be penalised unless the item is dangerous.
  • Aerosol containers are screened by airline baggage handlers; items that meet the rules proceed to the aircraft hold.
  • The CAA says all aerosol containers must have a fitted cap or locking device — CAA (aviation regulator).

Key rule: Caps on — always.

The trade-off

If your aerosol leaks or bursts during the flight, it’s removed and disposed of. For New Zealand travellers, this is rare — modern aerosol cans are built to withstand cabin pressure changes. But if you’re packing a large can of insect repellent for a trip to the Pacific, wrap it in a plastic bag just in case.

The catch: travellers should not assume that every aerosol will pass unchecked — industrial or flammable aerosols risk confiscation.

“Checked-in bags – each container must not exceed 500 ml [or 500g].”

New Zealand Civil Aviation Authority (aviation regulator)

“You’re welcome to pack your personal aerosols such as hairspray and deodorant in your carry-on or checked-in bags.”

Air New Zealand (national airline)

“The restrictions for aerosols do not apply to domestic flights within New Zealand.”

Aerosol Industry Council NZ (industry body)

For anyone flying out of New Zealand, the choice between carry-on and checked baggage is simple: if your aerosol is 100ml or less, it can go in your carry-on bag (as long as it fits in a single resealable 20cm x 20cm plastic bag). If it’s bigger than 100ml but under 500ml, it must go in checked baggage. If it’s over 500ml, leave it at home.

Frequently asked questions

Can I take sunscreen aerosol in checked baggage?

Yes, sunscreen aerosol is allowed in checked baggage as long as each container is 500ml (500g) or less. Sunscreen counts as a toiletry item, so it falls under personal use — CAA (aviation regulator).

Are aerosol canisters for cooking allowed?

Cooking aerosol canisters (e.g., cooking spray, whipped cream) are generally not allowed in checked or carry-on baggage because they contain flammable propellants. Check with your airline — Air New Zealand (national airline, restricted items).

Do I need to pack aerosols in a specific way (e.g., wrapped)?

It’s recommended to place aerosol cans in a sealed plastic bag to prevent leakage. The CAA requires all containers to have a fitted cap or locking device — CAA (aviation regulator).

Can I take multiple aerosol cans in checked baggage?

Yes, but each container must be 500ml or less. The NZ CAA does not specify a total quantity limit for checked baggage, but IATA rules (applied by most airlines) may cap the total at 2 litres for aerosols classified as dangerous goods. Check with your airline — CAA (aviation regulator).

What about aerosol deodorant in carry-on?

Aerosol deodorant in carry-on must be 100ml or less and fit inside a resealable 20cm x 20cm plastic bag. The total of all liquids-aerosols-gels must not exceed 1 litre — CAA (aviation regulator).

Are there differences for international destinations?

Yes, different countries may have stricter rules. For example, the US TSA allows aerosols up to 340g (12 oz) in checked baggage, while the EU follows IATA rules similar to New Zealand. Always check the destination country’s regulations — CAA (aviation regulator).

Can I take insect repellent aerosol?

Yes, insect repellent aerosol is allowed in checked baggage up to 500ml per container. Carry-on limit is 100ml. Make sure the cap is fitted securely — SCTI NZ (travel insurance provider).

For New Zealand travellers heading overseas, the rule of thumb is this: check the container size first, then decide which bag it goes in. For domestic travellers within New Zealand, the restrictions simply don’t apply — you can pack aerosols freely. The one exception: if your domestic flight departs from an international terminal, the carry-on rules still apply. Always check your airline’s specific restrictions before you pack, and when in doubt, put your aerosols in checked baggage.
