TSW Handles More than Just Customs
New Zealand's Trade Single Window isn't only a customs channel, it's the shared electronic gateway for Customs, the Ministry for Primary Industries, Maritime NZ, and the Ministry of Health all at once. That means a filing gap doesn't just risk a customs delay, it can hold up biosecurity or health clearance too. And TSW's rules keep moving: as of 1 April 2026, low-value goods levies shifted from a per-cargo-report basis to consignment-based charging, changing how fees get calculated on exactly the kind of high-volume, low-value shipments many forwarders handle daily.
CargoWise NZCS integration files declaration data directly through TSW, built around its current levy structure and multi-agency requirements, not a filing process that's fallen behind the April 2026 changes.
