For more than a decade I have asked DCC staff to plant at least some Family Friendly fruit trees since they plant hundreds of other trees annually, but so far without success.
As Mayor I will be able to push this catch-up with other NZ Cities much more effectively.

It is a good idea in theory. In practice you find that the trees only produce rubbish fruit if not properly cared for. Then they just litter the roadside/footpath with fruit that nobody wants.
