Kia ora from Aotearoa New Zealand,

The newly established User Group of Aotearoa New Zealand is interested in knowing more about the editing community within NZ, and those editors offshore who edit New Zealand pages/content. Is there any way of accessing data on the this to answer our questions (see below)?

Heather
