International products and services changes - FAQs

Sending a letter overseas

Due to the impact of COVID-19, airline capacity globally has decreased resulting in an increase in air freight charges. This, coupled with changes made by the United States Postal Service (USPS), has resulted in increases to the cost of international services we use. We have had to make the decision to pass some of this additional cost on. This decision has not been made lightly, particularly given the impact of COVID-19 and the challenges we know many are facing throughout New Zealand.

The required postage will increase for sending letters overseas.

* The increase in RRP of some postage included envelopes may differ from the increase in postage due to increases in other supplier costs. 

Sending parcels overseas

From 16 September 2020, the RRP will increase for the following services:

International Air Parcel

The RRP for International Air Small Parcel will increase by an average of 7%* and International Air Parcel will increase by an average of 10%*. 

International Courier

The RRP for International Courier will increase by an average of 7%*. 

International Express Courier

The RRP for International Express Courier will increase by an average of 5%.

* The RRP for sending parcels to the USA using International Air Small Parcel, International Air Parcel and International Courier services will increase considerably more than the average percentage listed.

Changes from 10g to 50g increments

We are changing the way we calculate postage. Postage will be charged in 50g instead of 10g increments. This applies to International Air Small Parcel, International Air Parcel, International Courier and International Express Courier items. All rates will be rounded up to the nearest 50g e.g. 160g rounds to 200g.

For example, the cost to send a 0.463kg item to Australia by International Air would be:

$13.6393 + (0.5kg* x $8.75) = $18.01

* Previously this would have rounded to 0.470kg

Changes to International services when sending to United States (USPS Changes)

Changes made by the USPS have resulted in increases to the cost of international services. These changes have a considerable impact on the price of sending a parcel to the USA when using our International Air Small Parcel, International Air Parcel and International Courier services.

Learn more about the USPS changes.

The price increase is more significant for items under 2kg as these items experienced a larger change in cost that other services. These changes better reflect the costs that USPS incur for delivery of these items.

These changes relate to parcels being sent from New Zealand to the United States via USPS. The rates for sending from the US to New Zealand are not set by NZ Post.

No, these changes impact a large number of postal operators around the world.

The pricing changes in the USPS rate structure only impacts the cost of sending your items from New Zealand to the US. Rates to other destinations are typically reviewed on an annual basis to reflect changes in costs.

The introduction of the new Zone US for sending documents and parcels to the USA ensures that these increases will only impact your shipping costs to the United States and not the other areas covered in Zone D

Introducing volumetric pricing 

We are implementing volumetric pricing for International Air and International Courier Items so the chargeable weight will be based on the greater of its actual weight or volumetric weight.

The minimum chargeable weight is still 2kg for International Air Parcel, 500g for International Courier Parcels and 250g for International Courier Documents.

Volumetric weight (kg) = height (m) x length (m) x depth (m) x 200


A parcel with dimensions 150mm (height) x 400mm (length) x and 600mm (depth)

(0.15m x 0.4m x 0.6m) x 200 = 7.20kg.

If the actual weight on the scales for this parcel is 4kg, then the customer would be charged at 7.20kg as the volumetric weight is greater than the actual weight of the parcel.

Changes to Electronic Advance Data (EAD) 

EAD is the electronic capture of consignment note information for transmission to the overseas destination, before the item leaves New Zealand.

We are requiring the electronic capture of sender, receiver and parcel content information on the consignment note and Customs declaration information for all international services (except International Air letters).

Learn more about the EAD changes.

The information is captured for the purpose of fiscal, risk, security and clearance in line with the national and international legislation. 

If we do not comply with these international requirements the item may not be able to enter the destination country. 

This requirement is not limited to New Zealand; all postal operators and other delivery service providers around the world are required to capture and transmit this data to all countries before items can be sent. 

A service fee of $5 (GST Zero rated) is included in the in-store price of sending International Courier, International Express Courier, International Air Small Parcel and International Air Parcel overseas to cover the electronic data capture cost, processing and administration fee.

No, items sent using the Print Postage tool on the NZ Post website don’t need to be scanned for EAD. Sender, receiver and parcel content information is sent electronically to the overseas postal service or organisation.

The information captured may be electronically transmitted to the destination postal administration and national government agencies (such as Customs) for fiscal, risk, security and border clearance purposes, in line with national and international legislation.
