Wellington conference and event venues that seat 450 or more delegates theatre-style, ranked live by capacity.
A 450-delegate conference sits in the upper-mid tier of Wellington's market, where the field narrows to purpose-built convention floors, the largest hotel ballrooms and the capital's civic and cultural halls. At this scale you are usually weighing a single large plenary space against venues that reach 450 only by opening divisible rooms — a distinction worth settling early, because it shapes sightlines, staging and AV.
Wellington's advantage for a group this size is its compact, walkable CBD: delegates move between venue, hotels and dinner on foot, which keeps transport out of the budget and shortens the day. The list below is generated live from our directory and ranked by theatre-style capacity, largest first. Theatre figures assume rows of seating with no stage or catering, so a central runway or in-room catering can reduce the usable number sharply — confirm the true figure for your layout.
Compare other delegate thresholds on the capacities index and browse every option in the venues directory. MICE keeps one national record so you can judge Wellington venues on capacity, layout and location rather than marketing copy.

The ranked list on this page shows every venue in our directory with a theatre-style capacity of 450 or more, and it updates as listings change.
It varies. Some venues reach 450 in a single hall; others only by opening divisible partitions. Confirm whether the figure is one contiguous space before booking.
No. Banquet capacity is lower than theatre because tables and service need more room. Check the banquet figure separately.
Yes. The capital regularly hosts national conferences at this scale, helped by a walkable CBD and a cluster of large hotels and civic venues.
