If you’re boarding an Air New Zealand flight soon and your power bank is a travel staple, there’s a change coming that might affect your charging routine. Starting December 9, 2025, the airline is rolling out stricter rules: a maximum of two power banks per passenger, each capped at 100 watt-hours, and an outright ban on in-flight charging during taxiing, take-off, and landing.

Can You Take a Power Bank on a Plane with Air New Zealand?

General Rule for Power Banks in Cabin Baggage

  • Power banks must be carried in hand luggage, not checked baggage (Aviation Security New Zealand).
  • Air New Zealand forbids power banks in overhead lockers; they must be under the seat or in the seat pocket (Air New Zealand official policy).
  • The battery terminals must be protected (tape or case) to prevent short circuits (Air New Zealand).

If you refuse to hand over a prohibited power bank at screening, you’ll be denied passage and the airline will be notified (Aviation Security New Zealand). The implication: compliance isn’t optional—it’s a condition of boarding.

Important

Non-compliance can lead to denial of boarding or confiscation of devices. Pack only compliant power banks.

What Is the Maximum Power Bank Size Allowed on Air New Zealand Flights?

Maximum Capacity: 100 Watt-Hours (Wh)

Air New Zealand sets a hard cap of 100 Wh per power bank (Air New Zealand lithium battery policy). Power banks between 100 Wh and 160 Wh require airline approval (Air New Zealand). Anything above 160 Wh is banned completely (Air New Zealand).

Maximum Quantity: 2 Power Banks Per Passenger

You may carry no more than two power banks in your cabin bag (RNZ). According to forum discussions, Air New Zealand also allows up to 20 spare batteries total, but the power bank count is capped separately (Geekzone forum).

Capacity reference for common power banks:

Power bank capacity (mAh) Typical Voltage (V) Watt-hours (Wh) Allowed on Air NZ?
5,000 3.7 18.5 Yes
10,000 3.7 37 Yes
20,000 3.7 74 Yes
27,000 3.7 100 Yes (borderline)
30,000 3.7 111 No (exceeds 100 Wh)
40,000 3.7 148 No (exceeds 100 Wh)
50,000 3.7 185 No (exceeds 160 Wh)

The trade-off: a 20,000 mAh power bank (74 Wh) is fine; a 30,000 mAh model (111 Wh) is not. If you’re close to the limit, check the watt-hour rating printed on the device.

Where Must I Store My Power Bank on an Air New Zealand Flight?

Under the Seat or Seat Pocket

  • Power banks must be placed in a cabin bag under the seat in front of you or in the seat pocket (Air New Zealand official policy).
  • They cannot be stored in overhead lockers due to fire risk (Stuff).
  • This rule applies during taxiing, take-off, and landing (Stuff).

Why this matters: lithium battery fires in overhead bins are harder to detect and contain (Aviation Security New Zealand). Keeping power banks within arm’s reach gives crew a faster response.

Can I Charge My Devices Using a Power Bank on an Air New Zealand Flight?

Charging Ban During Taxiing, Take-Off, and Landing

  • Air New Zealand bans the use of power banks for charging during taxiing, take-off, and landing (RNZ).
  • Use during cruise phase is generally permitted unless the crew states otherwise (Air New Zealand official policy).
  • The December 2025 rule update specifically prohibits charging in flight (Stuff).

The catch: even if you’re in the cruise phase, the crew can ask you to stop charging. It’s safer to assume your power bank stays in your bag until you’re at the gate.

The upshot

Air New Zealand’s new rules treat power banks as potential fire hazards, not convenience tools. For travelers, the consequence is clear: charge your devices before you board, and keep your power bank stowed.

The pattern: the stricter rules aim to eliminate any risk during critical flight phases.

What Are the New Air New Zealand Power Bank Rules from December 2025?

The changes effective December 9, 2025, tighten restrictions across several dimensions. Here’s a side-by-side comparison of the old vs. new rules.

Rule Before Dec 2025 From Dec 9, 2025
Max power banks per passenger Not explicitly capped (within 20 spare batteries) 2
Max capacity per power bank 100 Wh (standard IATA) 100 Wh (no change) – but stricter enforcement
Storage location Allowed in overhead lockers Only under seat or seat pocket
In-flight charging No explicit ban Banned during taxiing, take-off, and landing

What this means: Air New Zealand has moved from a relaxed interpretation of IATA guidelines to a strict, enforceable policy. Passengers should expect more frequent screening inquiries and a zero-tolerance approach.

Timeline: How Air New Zealand’s Power Bank Rules Evolved

  • Before December 2025: Air New Zealand allowed power banks in overhead lockers and did not have an explicit in-flight charging ban (Air New Zealand official policy).
  • December 4, 2025: Stuff.co.nz reports upcoming rule changes effective December 9, 2025 (Stuff).
  • December 5, 2025: RNZ publishes update confirming rule changes, citing safety concerns over battery fires (RNZ).
  • December 9, 2025: New rules take effect: max 2 power banks per passenger, 100 Wh limit, no in-flight charging, mandatory under-seat storage (Aviation Security New Zealand).

The implication: the airline has gradually tightened rules over a week, giving passengers little time to adjust.

“The new rules bring us in line with international safety standards and reduce the risk of battery fires on board.” – Air New Zealand spokesperson, RNZ, December 2025

“All spare batteries, including power banks, must be carried in cabin baggage only. Do not place them in checked luggage.” – Air New Zealand, Travelling with batteries and devices

For travelers flying Air New Zealand, the choice is clear: pack only one or two power banks under 100 Wh, keep them in your seat pocket, and don’t expect to charge during takeoff and landing—or risk losing your battery at security.

Frequently asked questions

Can I bring a power bank to New Zealand from overseas?

Yes, power banks are allowed in carry-on baggage when flying into New Zealand, subject to the same 100 Wh limit and two-per-passenger cap. Check with your departing airline for any additional restrictions.

What is the formula to convert mAh to watt-hours?

Wh = (mAh × V) / 1000. Most power banks operate at 3.7 V, so a 20,000 mAh bank gives roughly 74 Wh (20,000 × 3.7 / 1000).

Are laptop batteries covered under the same Air New Zealand rules?

Laptop batteries installed in a device are generally allowed in both carry-on and checked baggage. Spare laptop batteries (e.g., external power packs) are treated as spare lithium-ion batteries and must follow the 100 Wh carry-on rule.

What should I do if my power bank is damaged or swollen?

Do not take a damaged power bank to the airport. Contact your local hazardous waste disposal service. Air New Zealand and AvSec both prohibit damaged or recalled batteries from being carried on any flight.

Can I carry a power bank on Air New Zealand domestic flights?

Yes, the same rules apply to domestic flights. Power banks are allowed only in carry-on, max 100 Wh, max two units, stored under the seat or seat pocket.

Does Air New Zealand allow power banks with built-in cables?

Yes, built-in cables are fine as long as the battery itself meets the 100 Wh limit and is in carry-on. Ensure the cables are secured to prevent short circuits.

What are the rules for loose lithium batteries on Air New Zealand?

Spare lithium batteries (non-installed) are allowed only in carry-on. Each battery must be individually protected from short circuits (tape terminals or original packaging). The 100 Wh limit applies to each cell.
