Where to find large-capacity plenary venues in New Zealand for conferences and conventions of 500+ delegates.
Conferences of 500 or more delegates need genuine plenary capacity — a single space that seats everyone theatre-style, plus breakout rooms and exhibition or catering areas alongside. New Zealand's purpose-built convention centres and larger hotels in the main centres are the usual homes for events at this scale.
The fastest way to find them on MICE is the capacities index, where you can filter spaces by theatre, banquet or cocktail capacity and see which venues clear your delegate number. From there, each venue profile shows its full room inventory, nearby hotels for the room block, and transport around it.
For events this size, confirm the largest room's true seated capacity in your preferred layout, the availability of breakouts, load-in access for exhibitions, and the size of the accommodation block nearby — directly with the venue.
Live from the MICE directory, ranked by our data. Figures are indicative — confirm with each provider.

Most convention-scale venues offer breakouts and exhibition space alongside the plenary. Each venue profile on MICE lists its full space inventory.
