Import GST in New Zealand affects anyone bringing goods into the country, from occasional online shoppers to businesses importing at scale. Understanding when the Goods and Service Tax (GST) applies, who collects it, and how it works is essential to avoid unexpected costs, delays at customs, or compliance issues.

This guide breaks down how is import duty and GST calculated in clear, practical terms, covering rates, calculations, exemptions, certificates, deferment options, and common pitfalls, so you can manage import costs confidently and stay fully compliant.

Key Takeaways:

  • Import GST in New Zealand applies to most goods brought from overseas, ensuring fair taxation between local and imported products.
  • GST on imported goods is 15%, calculated on customs value plus duty, freight, insurance, and other applicable charges.
  • Businesses can reclaim GST tax on imports in New Zealand using the GST certificate if goods are for taxable activities.
  • Low-value imports (≤ NZD 1,000) are taxed at the point of sale, while high-value goods are charged at the border.
  • Deferred GST accounting allows eligible businesses to postpone GST payment, improving cash flow and simplifying compliance with New Zealand Customs rules.

What Is Import GST in New Zealand?

In New Zealand, the GST is applied to goods brought into the country from overseas. It is a 15% consumption tax levied on most products imported into New Zealand, similar to the domestic GST applied to goods and services sold within the country.

Import GST ensures fairness between local and overseas suppliers and generates tax revenue for public services. It applies whether you are an individual buying goods online for personal use or a business importing items for resale or commercial use. 

When Does Import GST Apply in New Zealand?

GST on imports applies whenever goods are brought into the country from outside, including items purchased online or imported for commercial purposes. The rules differ based on the value of goods, the type of importer, and who collects the tax.

Key scenarios where Import GST applies:

  • Low-value Imported Goods: For most low-value consignments (NZD 1,000 or less), GST on imported goods in New Zealand is charged at the point of sale by overseas sellers, online marketplaces, or redelivery operators registered with Inland Revenue (IRD). This covers common e-commerce purchases and ensures GST is collected upfront.
  • High-value Goods: When goods exceed the low-value threshold, GST on imports is collected at the border by the New Zealand Customs Service. Importers must pay GST before goods are released, unless a deferral arrangement applies.
  • Commercial and Business Imports: Businesses importing goods for resale or operational use are charged GST at importation. GST-registered businesses may later claim this back as input tax, supported by an Import GST certificate issued by Customs.
  • Goods Entering from Outside New Zealand: Unlike customs unions or VAT regions, New Zealand treats all overseas countries the same. Any goods entering New Zealand are considered imports, and GST applies regardless of origin.

How Import Duty and GST Are Calculated?

Understanding how import duty and GST are calculated is essential for estimating the total landed cost of imported goods. In New Zealand, Customs calculates charges in a specific order, and GST is applied after duty, and other costs are added.

  • Customs Value (CV): This is usually the price paid for the goods, converted to NZD, excluding international freight and insurance.
  • Import Duty (if applicable): Import duty rates depend on the product’s tariff classification and country of origin. 
    • Import Duty = Customs Value × Duty Rate
  • Value for GST (VFG): GST is not calculated only on the goods’ value. The GST on imports in New Zealand is charged on:
    • Import Duty
    • International Freight
    • Insurance
    • Any other Customs-related charges
  • GST Amount: This is the GST tax on imports in New Zealand, payable at the border unless GST was already collected at checkout for low-value goods.
    • 15% × Value for GST

Numeric Example

Assume you import commercial goods into New Zealand with the following details:

  • Customs value of goods: NZD 2,000
  • Import duty rate: 5%
  • International freight and insurance: NZD 300

Step 1: Calculate import duty

  • Duty= 2,000 × 5% = NZD 100

Step 2: Calculate the value for GST

  • Value for GST= 2,000 + 100 + 300 = NZD 2,400

Step 3: Calculate GST

  • GST= 15% × 2,400 = NZD 360

Total payable at import:

  • Import duty: NZD 100
  • GST on imported items: NZD 360
  • Total taxes: NZD 460

Import GST Rates in New Zealand

The standard rate for Import GST in New Zealand is 15%. This rate applies uniformly to most imported goods, ensuring consistency between domestic purchases and GST on imported goods. There are no reduced GST rates for import, goods are either taxed at 15% or are zero-rated/exempt under specific rules.

Standard Import GST Rate

This rate governs GST on imported items in New Zealand and applies to most commercial and personal imports, whether GST is collected at checkout (low-value goods) or at the border by Customs.

Zero-Rated or Exempt Categories (Selected)

While there is no reduced rate, certain imported goods may be zero-rated (0%) or exempt, meaning no GST is charged at import:

  • Exempt Supplies (no GST charged): Examples include certain financial services and donated goods imported by approved charities under specific conditions.
  • Zero-Rated Imports (0%): Some goods may be zero-rated due to their nature or use (e.g., qualifying goods for diplomatic use or specific international arrangements).

Low-Value Imported Goods

For consignments valued at NZD 1,000 or less, the New Zealand GST on imports is typically collected by overseas sellers or marketplaces at the 15% rate at checkout, rather than at the border.

Import GST Certificate

An Import GST certificate isn’t a separately named “certificate” issued by IRD, but rather the import entry documentation issued by the New Zealand Customs Service that shows GST was assessed and paid when goods enter New Zealand. This import entry is essential for GST‑registered businesses to substantiate claims when reclaiming GST.

What It Represents

When goods with a customs value of NZD 1,000 or more are cleared through Customs, the Electronic Cargo Clearance Document (ECC) or import entry includes details of any GST charged by Customs. This import entry acts as proof of GST paid and is used to support input tax claims in a business’s GST return.

Purpose of the Import Entry as a GST Certificate

For GST‑registered businesses, the import entry is used to:

  • Verify GST paid on imports (for goods entering New Zealand)
  • Serve as evidence for claiming back gst tax on imports in New Zealand as an input tax credit in the GST return, provided the goods are used for a taxable business activity.

How to Defer GST on Imports?

Eligible businesses can defer GST on imports to improve cash flow by postponing the payment until their GST return is filed, rather than paying GST upfront at the border.

Available Deferment Scheme: Deferred GST Accounting

New Zealand offers Deferred GST Accounting, which allows approved importers to account for GST on imported goods in their periodic GST return instead of paying it immediately to Customs.

Under this scheme:

  • No GST is paid at the time of importation.
  • The GST is simultaneously declared as output tax and claimed as input tax (if fully deductible), often resulting in a nil cash payment for that import period.

Eligibility Criteria

To qualify to defer GST on imports, a business must:

  • Be GST-registered in New Zealand
  • Have a good compliance history with IRD
  • Import goods for taxable business purposes
  • Meet Customs and IRD approval requirements

Deferred GST accounting generally applies to imports where GST would otherwise be payable at the border (typically consignments over NZD 1,000).

Registration Process

Businesses must apply to IRD for approval. Once approved:

  • Customs records the importer as a deferred GST user
  • GST is no longer collected at the import
  • Import details flow through to GST returns, supported by import documentation rather than immediate payment.

Reclaiming Import GST as a Business

Businesses that are GST-registered can usually reclaim for taxable activities. Reclaiming ensures businesses are not left bearing the cost of GST that ultimately relates to making taxable supplies.

Who Can Reclaim Import GST

You can reclaim GST on imported items in New Zealand if:

  • Your business is registered for GST with IRD.
  • The imported goods are used to make taxable supplies (not exempt supplies).
  • You have paid GST at the border or accounted for it under a deferred scheme.

Documentation Requirements

To reclaim New Zealand GST on imports, businesses must retain valid import records, including:

  • The Import GST certificate issued by the New Zealand Customs Service
  • Import entry or clearance documentation
  • Supplier invoices and transport records supporting the import value

These documents substantiate the amount of GST tax on imports in New Zealand claimed as input tax.

Accounting Treatment

When completing a GST return:

  • The import GST amount is included as input tax.
  • If the business uses Deferred GST Accounting, the same amount may be recorded as both output and input tax in the same return.
  • Accurate treatment depends on how import duty and GST are calculated and whether GST was paid upfront or deferred.

Timelines for Reclaiming

  • Import GST is reclaimed in the GST return period covering the date of import or accounting entry.
  • Businesses must keep import records for at least seven years.
  • Delayed or missing documentation may result in denied or deferred claims.

Common Challenges & Compliance Mistakes

Managing import GST in New Zealand can be complex, and errors often lead to delayed customs clearance, denied GST claims, or penalties. Below are the most common compliance issues businesses face:

  • Incorrect Customs Value Declaration: A frequent mistake is understating or miscalculating the customs value, which directly affects how import duty and GST are calculated. Ensure the declared value reflects the transaction value adjusted according to Customs valuation rules. Retain supplier invoices and shipping documents to support the valuation.
  • Missing or Incomplete Import GST Certificate: Businesses often fail to obtain or retain the certificate, making it impossible to reclaim GST tax on imports as input tax. Download and store the certificate for every qualifying import. Confirm your customs broker provides complete import documentation.
  • Misclassification of Goods: Incorrect tariff classification can lead to applying the wrong duty rate, which then impacts GST because it is calculated after duty is added. Use the New Zealand Working Tariff to identify the correct classification. Seek a Customs ruling if classification is uncertain.
  • Incorrect Use of Deferred GST Accounting: Some businesses incorrectly apply or continue using deferred GST accounting without approval, leading to non-compliance. Confirm active approval from IRD before you defer GST on imports. Regularly review eligibility and compliance status.
  • Claiming GST on Non-Taxable Imports: Claiming input tax on goods used for exempt activities is a common error that can trigger IRD audits. Verify the end use of imported goods before claiming GST. Separate taxable and exempt import costs in your accounting system.

By proactively addressing these issues, businesses can reduce compliance risks, ensure accurate reporting, and maintain smooth customs clearance and GST recovery processes.

Import GST for E-commerce & Cross-Border Sellers

New Zealand has specific rules for import GST that directly affect e-commerce businesses and cross-border sellers supplying goods to New Zealand customers. These rules determine who must charge GST, when it is collected, and whether GST is paid at checkout or at the border.

Low-Value Imported Goods Rules

For most low-value consignments valued at NZD 1,000 or less, GST is collected at the point of sale, not by Customs. Overseas sellers, online marketplaces, and redelivery operators must register for New Zealand GST and charge 15% GST to consumers at checkout.

This regime applies to:

  • Goods sold directly by overseas sellers to New Zealand customers
  • Sales made through online marketplaces
  • Goods redirected to New Zealand via mail-forwarding services

Marketplace Responsibilities

When sales are facilitated through an online marketplace, the marketplace operator is generally treated as the supplier for GST purposes. The marketplace is responsible for:

  • Registering for GST in New Zealand
  • Charging and collecting GST on imported items in New Zealand
  • Filing GST returns and remitting tax to IRD

High-Value Goods

For consignments exceeding NZD 1,000:

  • GST on imports in New Zealand is collected at the border by Customs.
  • The buyer (importer of record) is responsible for paying GST and any applicable duty.
  • Customs applies the standard import calculation rules, including how import duty and GST are calculated.

These rules are essential for cross-border sellers to remain compliant and avoid double taxation, unexpected customs charges, or denied GST recovery when selling into New Zealand.

FAQs About Import GST in New Zealand

1. Why am I being charged Import GST even after I already paid GST at checkout?

This usually happens when Customs cannot verify that GST was correctly charged at checkout by the overseas seller or marketplace. If the seller did not include their GST registration details or the parcel data was incomplete, Customs may assess Import GST again at the border.

2. Why did my package get held by customs due to unpaid GST, and how do I release it?

Packages are held when GST on imported goods in New Zealand (and any duty) has not been paid. To release the goods, you must pay the assessed amount via the courier or the Customs payment process. Once paid, the clearance proceeds.

3. What should I do if the courier charged me the wrong Import GST amount?

Request a detailed breakdown from the courier showing how import duty and GST are calculated. If incorrect, you can seek a reassessment or lodge a dispute with Customs, supported by invoices and shipping documents.

4. Why is Import GST higher than expected compared to the item price?

GST is calculated on the total landed value, not just the item price. This includes shipping, insurance, and duty, which often increases the taxable base.

5. What happens if I refuse to pay Import GST? Will the package be returned or destroyed?

If Import GST is not paid, Customs may arrange for the goods to be returned to the sender or destroyed, depending on the carrier’s policy and timeframe. Storage and return costs may still apply.

6. Can I get a refund on Import GST if I return the imported item to the seller?

Yes. If imported goods are exported or returned, you may apply for a refund, provided you meet eligibility conditions and supply proof of export or return.

7. How do I dispute Import GST charges if customs misclassified my goods?

You can request a review by Customs and provide evidence such as product descriptions, technical specifications, or tariff references. Misclassification affects the duty and GST tax, so corrections can reduce the GST payable.

8. Why am I paying GST twice when importing goods into New Zealand?

Double GST usually occurs when GST is charged at checkout and again at the border due to missing or incorrect seller information. In such cases, you can seek a refund from either the seller or Customs, depending on where the error occurred.

9. Does Import GST apply to second-hand, refurbished, or used goods bought from abroad?

Yes. GST on imported items in New Zealand applies regardless of whether goods are new, used, or refurbished, unless a specific exemption applies.

10. How long does it take to get a refund if I was overcharged Import GST at customs?

Refund processing times vary, but once approved, refunds are typically issued within 20–30 working days, depending on case complexity and documentation completeness.
