Seismic Strengthening
Earthquake-prone building notices
Wellington City Council has recently completed seismic assessments across the portfolio leased by Te Toi Mahana which show that parts of some buildings are below the 34% New Building Standard’s (NBS) threshold. This means these buildings do not meet current earthquake standards and need to be strengthened.
The buildings have been assessed as earthquake-prone because earthquake standards have become more stringent and not because the buildings are any less safe than they have been in the past.
The buildings that need to be strengthened are:
-
Berkeley Dallard, located at 46 Nairn Street, Mount Cook.
-
144, 146, 148 Daniell Street, Newtown.
-
Hanson Court (Blocks A, C, D & E), located at 80 Hanson Street & 3 Hutchison Street, Newtown.
-
Kōtuku (Blocks A, B,C & D), located at 5 Kemp Street & 609 Evans Parade, Kilbirnie.
-
Pukehinau (link bridge only), located at 4 Brooklyn Road, Aro Valley.
-
Whare Ahuru Flats, located at 16 Glenmore Street, Thorndon.
Plans to strengthen buildings
Wellington City Council plans to strengthen each building to ensure it meets the new earthquake standards.
More information will be provided later this year about exactly when and how this work will be undertaken, and the impacts on tenants. Te Toi Mahana will work closely with all tenants to ensure the impact of this work is minimised and necessary support is provided

Frequently Asked Questions
What is an earthquake-prone building notice?
An Earthquake-prone building notice (yellow sticker) identifies a building, or part of a building, as being earthquake prone and needs to be strengthened.
The notice gives each building an earthquake rating against the New Building Standard (NBS). A building is earthquake-prone if it has a seismic rating of less than 34% of the NBS.
Is it still safe to live in my building?
An occupancy risk assessment has taken place, and we have been advised that is appropriate to continue to live in your building.
Are there any other earthquake-prone buildings in the city?
Yes, around 600 buildings in the city need earthquake strengthening.
What are the plans to strengthen my building?
Council and Te Toi Mahana will share plans to strengthening each building later this year. Dates will vary for individual buildings, as will the length of works and number of people impacted.
The Council will lead the plans to strengthen the building while Te Toi Mahana manage the impact on tenancies and any rehousing requirements.
Is my tenancy secure?
Yes your tenancy is secure with us. We will support all our tenants throughout this process and work to minimise the impact that this may cause.
Does it mean I’ll have to move out?
If you live in one of the affected properties, you may be required to move out temporarily. Council is currently working on a plan for strengthening each building and we will share more information later this year.
When and how can I find out more?

Can you give further details about my property?
Berkely Dallard
Berkely Dallard has an earthquake rating of 30% NBS for both North and South buildings. The primary structural weaknesses of both buildings relate to concrete walls above Level 9.
144, 146 and 148 Daniel Street
These three buildings have a rating of 15% NBS due to their chimneys. The chimneys may fall away from the building during an earthquake posing a hazard to pedestrians outside the building. However, the chimneys are not expected to be a hazard for people inside the building during such an event.
Hanson Court
The tower block, Block B, has been assessed as having a seismic rating of 45% NBS and is not considered to be earthquake prone. Blocks A, C, D and E have each been rated at 25% NBS, primarily due to the lack of lateral restraint to the upper-level concrete wall elements.
Kotuku Apartments
Kotuku Apartments (Blocks A, B, C & D) each have a seismic rating of 25% NBS due to inadequate connections to the ground beams beneath each block.
Pukehinau
Block A nor Block B are not considered to be earthquake prone. Only the link bridge between the two buildings is considered to be earthquake prone and has a rating of 15% NBS due to the connection at the Block B end.
Whare Ahuru Apartments
The Whare Ahuru Apartments have a seismic rating of 15% NBS due to connection between the original two-story building and the additional third level.
