1872 Following a conversation between the Hon. E.C.J. Stevens and Sir Julius Vogel, the first bill providing for a Public Trust Office is introduced by Vogel. The idea is for the state to back an institution which can provide a trustee who is permanent, solvent, and qualified to act, an uncommon combination in the early years of settlement in New Zealand.
1872 A redrafted Public Trust Bill proposed by Vogel becomes law.
1873 The Public Trust Office is established. The first state-backed institution of its type in the world, it, becomes the model for similar systems in England, Canada, Australia and Fiji.
1876 A start is made on reclaiming the the Thorndon shoreline, where the Public Trust Office Building will eventually be built.
1894 Government architect John Campbell is approached to prepare plans for the Public Trust Office Building. Concerns are raised over its proposed location – alongside Government Buildings.
1899 The annual Appropriation Act includes authority for the erection of a building and the provision of office accommodation for the Public Trust Office, the cost being met by the Office from accumulated profits.
1904 Reid Brothers of San Francisco is commissioned to prepare plans for a building on the Lambton Quay site on which the Public Trust Office Building will eventually sit.
1905 John Campbell prepares plans dated October 1905 for the Public Trust Office.
1906 Following the devastating San Francisco earthquake, John Campbell redraws his plans to incorporate a steel frame. The successful tender for construction is submitted by J. and A. Wilson – £40,780 (more than $6.5 million in 2015).
1907 Building work begins on the Public Trust Office.
1909 On Wednesday 9 June, the Public Trust Office Building is officially opened by Prime Minister Sir Joseph Ward.
1911 The building is illuminated and decorated for the coronation of King George V.

1919 Robert Triggs, the Public Trustee, requests authority to buy additional buildings in Stout and Ballance streets to accommodate his growing staff.
1922 Further renovations to the building are undertaken.
1923 An earthquake cracks plaster in the building.
1926 In May an immense beam above the Legal Branch’s work area falls down – probably as a result of damage during the 1923 earthquake. Fortunately this happened at the weekend and no staff were injured.

1926 More vaults are added to the building; these are designed ‘to stand intact if the whole building collapsed’.
1927 The beams above the Legal Branch and the concrete floors are strengthened, with ‘light angled furring’ added to the steel around the girders.
1932 On 11 May the Public Trust Office Building is one of many in Wellington attacked by an angry mob of unemployed workers. Two windows are smashed and a chisel is hurled into the building. Staff close and lock the vaults in case of invasion, but the mob moves on without further incident.

The Public Trustee has a great deal of difficulty finding suitable replacement windows.

1983 Riddiford Holdings purchases the building and undertakes major re-strengthening and minor refurbishment, using engineering firm Smith Leuchars and consulting architect Keith Wilson.

Centred 10 kilometres south-east of Seddon, close to Lake Grassmere, this causes significant damage to buildings in Seddon and nearby towns.
