1939 - 1940: Centennial Exhibition
Over six months in 1939 and 1940 Wellington hosted the New Zealand Centennial Exhibition, celebrating a century since the Treaty of Waitangi signing.
Despite the outbreak of war, the exhibition was a lavish affair. Held on 55 acres of land at Rongotai it featured three exhibition courts, grand Art Deco-style edifices and a hugely popular three-acre amusement park dubbed Playland.
When the exhibition closed in May 1940 more than 2.5 million people had passed through the gates.
US Marines marching in formation down Lambton Quay, 1942
1942: First arrival of US Marines
Four months after the Japanese bombed Darwin in February 1942, 20,000 US Marines arrived in Wellington. They entered the harbour on 14 June 1942 on the battered USS Wakefield. A band was waiting for them on King's Wharf, playing the Marine Corps hymn, 'From the halls of Montezuma, to the shores of Tripoli...', as they were the famous marines of the 1st Corps Division.
Though most Marines were in transit to or from combat zones in the central Pacific, they would have been available to defend New Zealand.
From the New Zealand perspective the Americans strengthened New Zealand's defences against possible Japanese attack; while the Americans saw New Zealand as a valuable source of supply and a staging post for operations against the Japanese in the Pacific.
The Marines were mainly housed in military camps in Paekakariki, Trentham and the Wairarapa, with smaller camps and hospital facilities in Wellington city.
Though tensions occasionally ran high between local men and the visiting Americans (leading in one case to the infamous 'Battle of Manners Street' riot in 1943), many life-long relationships were forged.

Motorway construction, Bowen Street and Hill Street, 1970
1967 - 1972: Urban motorway construction
In the late 1950s an urban motorway skirting the city's Western foothills was mooted by the City Council.
Following years of backroom politicking, construction began in 1967. The first stage was opened in 1969 amid a chorus of strident opposition. Construction finished in 1972.
A large section of historic Thorndon was demolished to accommodate the new motorway. In addition, the roadworks bisected historic Bolton Street Cemetery with thousands of settler graves having to be exhumed.
