International Bulk Mail

A cost effective way to send large amounts of letters and documents internationally by International Air with a delivery target of three to 10 working days.

International Bulk Mail is available to New Zealand Post Account customers who post large amounts of mail at the same time - it offers greater flexibility with weight and size limits and can cut back administrative time and costs.

Key benefits

  • Flexibility: each letter has a maximum allowable weight of 500g. Oversized printed material and parcels have a maximum allowable weight of 1kg.
  • Easy to use: only sort by International Bulk Mail destination zone.
  • Items based on actual weight: prices are based on the weight and destination of your items. You only pay for what you send, up to the next 10g increment for each item.
  • Zero-rated GST: this saves you administrative time in reclaiming GST and improving cash flow.*

*The cost of domestic air freight, if requested, will attract GST.

What can I send?

  • Letters up to 500g per letter.
  • Oversized printed matter up to 1kg per item.
