Steve Allen, was performed by a mass choir, as well as 'What the world needs now is love'. A Māori concert group then performed action songs and a haka, before the teams march past. The athletes then took the oath and Sylvia Potts, the runner who fell mere meters from a gold medal finish in the 1970 Games, entered the stadium with the Queen's Baton. It was presented to Prince Philip who read the message from the Queen declaring the 1974 Christchurch 10th British Commonwealth Games open. The Commonwealth flag was then marched in and hauled up with a 21 gun salute. Broadcasting The Games were also an important milestone in New Zealand television, marking the introduction of colour television. However, due to the NZBC's limited colour facilities, only athletics, swimming, and boxing could be broadcast in colour. Meanwhile, paralleling the Television coverage, the National Film Unit produced Games '74, a fine feature-length documentary of the Christchurch games (and the many events) in full colour. This has since been restored and is available on DVD. Legacy Economic aspects Christchurch was (and still is) the smallest city to host the modern televised Commonwealth Games. This was the first games that tried using the "Olympic" look with a standard colour scheme for facilities, passes, flags, stationery, and above all uniforms (which wearers only borrowed, but could buy outright as a memento thus helping keep costs down).

It is still copyright owned by Christchurch City Council but is allowed for free use unless for commercial gain. Badges, lapels, stationery and postcards are still in re-manufactured circulation. This was also the first time that a city had asked the Games Federation to allow commercial advertising. This was voted down as the Federation feared that advertising by big corporations would remove focus away from the amateur ethos of the Games. As no commercial hoardings were allowed, Christchurch got around this with the use of "sponsorship", one example being General Motors providing a lease fleet of Holden HQ Kingswood sedans that would be sold off after the games. The cars are now sought after by private and museum collectors and have depreciated little in value. Air New Zealand allowed large NZ74 symbols to be placed on the fuselage sides of the airline's
