The National Symphonic Orchestra of New Zealand.

They featured in the 1996 musical event known as ENZSO led by Eddie Rayner, in which the songs of Split Enz were arranged for the full New Zealand Symphony Orchestra with a number of different singers, including Dave Dobbyn. It was wildly popular, selling 45000 copies in New Zealand and 200000 in Australia.

In New Zealand we don't really have a large enough base of classical music fans to support a complete, full-time orchestra, but open-air concerts in parks are wildly successful in the summer, attracting up to a hundred thousand people. Often the music is a mixture of classical standards, new pieces, orchestral arrangements of popular music and topical pieces (christmas corals at christmas, for example).
