Shipping & Delivery

At Zilion, we understand that getting your products quickly is just as important as the quality of the products themselves. That’s why we partner with New Zealand’s most reliable logistics providers like Zappy, Post Haste, NZ Couriers, and NZ Post, to ensure your order arrives safely and swiftly.


How do I track my order?

Once our team has packed and dispatched your order, you will automatically receive a shipping confirmation email. This email includes a unique tracking link so you can monitor your parcel’s journey in real-time.

You can also track your shipments directly through our partner portals at Zappy, Post Haste, NZ Couriers or NZ Post using the tracking number provided.

Using the Shop App?
If you have a "Shop" account, you can track your Zilion orders seamlessly. By connecting your email to the Shop app, your delivery status will update automatically in your orders tab. You can also manually add your tracking number to the app for instant notifications.


Why isn’t my tracking link updating?

Don’t worry! After your parcel is dispatched, it needs to reach the courier depot for its first scan. It can take up to 24 hours for tracking details to go live on the Zappy, Post Haste, NZ Couriers or NZ Post systems. If you don’t see an update immediately, please check back the following morning.


What are the shipping costs?

We aim to keep our delivery rates fair and transparent for all New Zealanders:

  • FREE Shipping: On all orders over $85.

  • Standard Metro Delivery: $7.99

  • Rural Delivery: $7.99


What are your delivery timeframes?

We prioritize speed! We offer same business day dispatch for all in-stock items on orders placed before 09:00 AM.

  • Metro Deliveries: 1–4 business days.

  • Rural Deliveries: 3–7 business days.

Please note: During high-volume sale periods or public holidays, there may be slight delays. Orders containing "Dangerous Goods" (like aerosols or certain hair chemicals) may also require additional transit time due to safety regulations.


Can I change or cancel my order?

If you realize you need to make a change, please email us immediately at care@zilion.co.nz with your order number. If your order hasn't been picked up by our delivery partner yet, we will do our absolute best to accommodate your request. Once a parcel has been dispatched, we are unable to modify it.

 

Do you deliver to P.O. Boxes?

No! Because our delivery partner(s) do not deliver the cosmetics to P.O. Boxes. Please ensure you select the appropriate shipping method and correct delivery details.


Why did I only receive part of my order?

To get your items to you as fast as possible, we may split orders into multiple shipments if items are located in different areas of our warehouse or some of the products got damaged while packing or are not available at the moment due to any reason.


How will I know where the rest of my items are?

If your order is split, you will receive a separate tracking link for each parcel via email. Please check all shipping emails before contacting support, as the rest of your items are likely just a few stops behind!

 

Do you Offer Pickup?

Currently, we do not offer pickups.

Do you ship internationally?

Currently, Zilion is focused on serving our local community. We ship New Zealand-wide only and do not offer international delivery at this stage.
