After a few frustrating incidents of getting lost while trying to find interclub venues, I made this google map of all the tennis clubs in Auckland. Then I realised I had no idea how to announce it for the benefit of other players.
No one was going to find it by googling because user created maps don't appear to be searchable. The official internet organs of NZ tennis are firmly Web 1.0. There are sports forums out there such as sportsfreak.co.nz but these tend to be of the armchair variety.
Eventually I intend to expand it to cover the whole country.
