But scratch beneath the surface and the picture doesn't look quite so healthy.
While 9 per cent of our marine environment is available for trawl fishing and 12 per cent is subject to oil and gas permits, only half of 1 per cent has been set aside as marine protected areas.
The target to which our Government is committed is 10 per cent, and many experts believe we should aim for at least twice as much.
Size is another factor. Chile's largest marine reserve is 150,000 sq km while the UK's is 636,600 sq km. New Zealand's largest marine protected area is the existing Kermadecs Marine Reserve, which is just 7480 sq km.
As well as the quantity and size, the definition of what counts as a protected area also leaves something to be desired.
For example, "cable and pipeline zones" are counted as part of New Zealand's contribution to marine protected areas.
To his credit, Conservation Minister Nick Smith has pushed marine conservation up the political agenda in 2014 and is committed to establishing more marine reserves this year.
Marine protection for parts of the ocean around the sub-antarctic islands and a 5.1 sq km reserve south of Akaroa harbour have been announced, and there are more to follow. However, while welcome, these areas are relatively small. At the current rate of implementation it will take more than 800 years to achieve the international target.
Yet our Government could do something really significant for conservation: by committing to establishing a 620,000 sq km Kermadecs ocean sanctuary in our own EEZ, which would be one of the world's largest no-take marine protected areas. It is one of the last pristine ocean environments.
WWF believes that the Kermadecs Ocean Sanctuary would show the world that we're a global player and it would properly justify a seat for New Zealand at the top table of ocean governance. So come on Murray and John; how about it?
