PaulBags: There's a kiwibank sponsored will autoform, I don't have the link handy.
Is that the one available to Kiwibank business customers? My understanding is that (or at least was) the free online will service was not available to standard customers.
Anyway, my wife set up her business accounts with KB, so we decided to take advantage of the free will service. Ironically, as soon as we answered "yes" to her holding shares in a business they said it was too complex for the free service, so we'd have to pay for bespoke wills! At that point it was easier just to use a local lawyer...
