A live, ranked list of New Zealand conference and event venues with theatre-style capacity for 300 or more delegates.
Once a conference passes the 300-delegate mark, the shortlist narrows quickly. You are no longer choosing between meeting rooms — you are looking for purpose-built plenary halls: convention centres, arena function spaces, large hotel ballrooms and multipurpose event centres that can seat a full audience in one room, theatre-style, without splitting the group.
New Zealand's supply at this scale is concentrated but genuinely national. Auckland's NZICC and SkyCity, Wellington's Tākina and TSB Arena, Christchurch's Te Pae, and a spread of stadium and showground venues from Hamilton to Dunedin all clear 300 comfortably — and many go far beyond it. The trade-offs at this size are practical: ceiling height and sightlines for staging, load-in access for AV and exhibition build, break-out rooms nearby, and enough hotel rooms within walking distance to house the crowd.
The list below ranks real venues on the MICE directory by their largest theatre-style capacity. Use it as a starting shortlist, then confirm the true usable capacity for your format directly with each venue — a room's theatre maximum drops once you add a stage, screens, catering stations or a runway. Compare options in the venues directory and the capacities index.

Dozens, though they cluster in the main centres. The ranked list on this page shows current venues on the MICE directory that meet the threshold.
No. Banquet (seated dinner) capacity is usually lower than theatre, because dinner rounds and service space take more floor area. Always confirm the layout you need.
Treat it as a maximum. Staging, AV, exhibition and catering all reduce usable seats, so confirm the real figure for your run-sheet with the venue.
