Non-fragile rural parcels will be sent by post. You can upgrade to have these items delivered by courier which will often be faster and will be tracked.
If your item will be despatched to a North Island urban location on a Friday, or to a South Island urban location on a Thursday, then you can choose to pay the Saturday delivery fee and your parcel should be delivered on Saturday.
Items sent to the South Island are done so by economy. This usually takes at least 2 days. You can choose to upgrade to airfreight which should be overnight to urban locations.
These delivery upgrades are not eligible for discounts.
