Welcome to the 'verse @Leighghunt ! Do we know each other from CreativeCommons Aotearoa/NZ?
One of things I'm proud of from my time promoting CreativeCommons Aotearoa/NZ is the releases of LINZ map data under a CC license. Thanks mainly to the fantastic #OpenGeo community here. This could have become another thing we had to pay for (again), like the documentation of those standards. Instead, the whole country has great coverage in Open Street Map, and any other project is free to use a digital map of Aotearoa.
