Marlborough is well serviced by the state highway and local roading infrastructure, the rail link south from Port Picton and the export wharf at Shakespeare Bay.

The funding of local road upgrades at time of harvest is an issue that the MFIA and the local roading authority, Marlborough Roads, continue to discuss and look at ways of resolving. Marlborough Roads have been successful in obtaining "Alternatives to Road" ATR funding from central government for some log barging operations in the Marlborough Sounds.

Tug and barge services transport logs from forests in the Marlborough Sounds to Picton and Havelock ports, for further transport to local mills for processing or for re-export as logs. On a few occasions logs have been barged to the North Island from the outer Marlborough Sounds.
