Join us to celebrate a very big building's very big birthday!

Old Government Buildings turns 150 this year. Opened in 1876, Pōneke's most eye-catching Neo-Renaissance icon is one of the world's largest wooden buildings. Once home to the entire Wellington-based civil service, today the building houses Te Herenga Waka Victoria University's Faculty of Law, and is very proudly cared for by Heritage New Zealand.

We're celebrating this big anniversary with a day of tours, talks, family activities, competitions, and, of course, birthday cake!

Visit our website for a developing schedule of events, and to book heritage tours and special attic tours.

This event is proudly presented by Heritage New Zealand Pouhere Taonga as part of Wellington Heritage Festival 2026.
