New Zealand trans-Tasman and deep-sea RoRo exports use a band rule, not always "empty only". Most NZ forwarders specify between 10% and 25% tank — but leaking vehicles and over-filled tanks are rejected.
NZ RoRo fuel requirements
- Typical range: 10–25% tank for trans-Tasman RoRo (confirm with your carrier)
- Must not leak — petrol, diesel, or oil leaks = no load
- Working fuel gauge required
- Deep-sea / container: often stricter — many require empty tank
Why the rule exists
RoRo vessels carry vehicles as cargo under maritime dangerous goods rules. Too much fuel increases fire risk on enclosed decks. Ports of Auckland, Tauranga, and Lyttelton enforce carrier intake standards at delivery.
When you need a full drain
- Your forwarder specifies empty tank
- You're exporting containerised (not RoRo)
- Tank is above carrier maximum
- Vehicle failed leak check and needs line purge
How to comply
- Get written fuel limits from your shipping agent
- Book pre-export drain if above limit or if empty tank required
- Complete MPI clean before port delivery (separate from fuel)
- Allow 24–48 hours before sailing cut-off for drain and haulage
New Zealand export requirements (related)
Beyond fuel, NZ vehicle exports typically require:
- Clean vehicle — MPI biosecurity inspection; mud, seeds, and soil can fail inspection
- Running condition for RoRo — drivable with working brakes and steering unless containerised
- Customs export entry via your freight forwarder
- No personal effects in RoRo — cabin must be empty except spare tyre and jack unless shipping container
