What this solves

A Cook Strait ferry crossing is a real Aotearoa decision. The ferry is a 3-hour voyage between Wellington and Picton, with a scenic Marlborough Sounds approach. The alternative is a 12+ hour drive around via Taranaki and the Lewis Pass, plus 1,100 km of fuel and one night of accommodation.

Most online ferry calculators only show the headline ticket. Real cost depends on the vehicle category, cabin choice, number of passengers, peak season uplift, and whether a pet is in a vehicle deck or in a pet cabin. This tool stacks those line items and shows you the three realistic options side by side.
