The biggest conference and event spaces in Blenheim and across Marlborough, ranked by theatre-style seating capacity.
Marlborough is best known for its wines, but Blenheim anchors a compact, well-connected events region at the top of the South Island. Delegates can fly into Marlborough Airport or come across on the Picton ferry, and the district pairs purpose-built halls and sports-and-events centres with a cluster of cellar-door and vineyard settings. The list below ranks Marlborough's conference and event spaces by theatre-style capacity, so you can see at a glance which rooms can seat your plenary before you shortlist.
Theatre capacity is the fastest way to compare rooms, but it is only the starting point. The same space will hold far fewer people once you add a stage, catering stations, a dance floor or cabaret rounds, and a ceremony layout differs again. Treat the ranking as a filter for the plenary session, then confirm the true usable capacity for your specific layout — along with ceiling height, pillars, natural light and load-in access — directly with each venue. For wine-country programmes, remember that the headline function room and the barrel hall or lawn you want for the gala dinner may have very different limits.

The ranked list above shows Marlborough's spaces ordered by theatre-style capacity, so the room at the top is the largest on record. Capacities are updated as venues are verified, so check the current listing rather than relying on a single named venue.
It depends on the room and the layout. Theatre seating fits the most people; banquet, cabaret and classroom layouts fit fewer because of tables, staging and circulation space. Use the theatre figure to shortlist, then confirm the usable number for your exact setup with the venue.
Several cellar doors and vineyard estates offer function spaces suited to dinners, receptions and smaller meetings. Capacities are generally more modest than a dedicated conference hall, so confirm seated-dinner limits, wet-weather options and transport for delegates.
Marlborough Airport has direct domestic flights, and the Interislander and Bluebridge ferries connect Picton — about 30 minutes north — to Wellington. Factor transfer time and coach options into your programme if you are moving a large group.
Contact the venue with your date, headcount and preferred layout. Ask for a floor plan, confirm whether the figure includes staging and catering space, and check accessibility, parking and any noise or finish-time restrictions before you commit.
