Nelson Airport: Take eBus Route 4/airport service into central Nelson rather than paying for a shuttle: roughly 20–25 minutes to the CBD and about NZ$2–4, depending on fare/payment. Daytime services are about every 30 minutes, but the last airport departure is early evening (listed as 6:22pm), so a late arrival means pre-booking a taxi or shuttle.
Nelson InterCity coach stop: InterCity is the useful long-distance link, particularly from Picton (for Cook Strait ferries), Blenheim and elsewhere on the South Island. Nelson has no passenger rail station. Coach arrivals are close enough to the compact central city that a central hotel is usually a walk or short taxi away; use a taxi for Tahunanui, Stoke, Richmond or luggage-heavy arrivals.
