Conference venues for 400 or more delegates in New Plymouth and Taranaki

MICE editorial — 03 September 2026

The New Plymouth and Taranaki venues with a single space seating 400 or more delegates theatre-style, ranked live by capacity.

Stepping up to 400 delegates narrows a conference's options sharply: the plenary needs one room that seats everyone theatre-style with clear sightlines, which leaves only a region's largest halls. The list below ranks New Plymouth and Taranaki venues seating 400 or more delegates in theatre layout, largest first, live from the MICE directory.

New Plymouth anchors Taranaki's events scene, and at the 400-plus-delegate level the field comes down to the region's main performing-arts, stadium and conference spaces. Because that is a short list, confirm the genuine theatre capacity, sightlines and any pillars with each venue, and check whether the same room must also serve as your catering or exhibition space — using it twice changes what really fits. Booking early also protects the accommodation a group this size will need.

Compare the numbers on the capacities index, browse the venues directory, or check the events calendar for clashes first.

Frequently asked

How many New Plymouth and Taranaki venues seat 400 or more delegates?

The ranked list above draws live from the MICE directory and shows every listed venue in the region with a single space seating 400 or more delegates theatre-style. At this size it is a short list of the largest spaces.

Does the ranking count one room or combined rooms?

It ranks a single space in theatre layout, because a plenary needs everyone together in one room. Capacities reached by joining rooms are counted separately.

Will a 400-delegate hall also fit exhibition and catering?

Not necessarily. If one room must host the plenary plus a trade display or seated meals, the usable delegate number drops. Ask the venue how it sequences these.

Why is early booking important at this size?

Large regional rooms and the accommodation blocks around them are limited and get held well ahead. Securing dates early protects both venue and hotel availability.

Should I look at venues just under 400?

If your numbers are close, review venues rated slightly lower too, since final attendance often lands below early forecasts. The capacities index makes adjacent thresholds easy to scan.
