He's brought his Labour values to the top table, too, as many mums and dads will tell you on a stinking hot Auckland day when they take their kids to the free swimming centres pioneered by Len and Sir John Walker.
The very absence of divisive issues is also a tribute to Mark Ford, who led the Auckland Transition Agency, which set up the SuperCity.
His plan has rolled out flawlessly.
Mark faced flak recently for taking on too much as chair of troubled Solid Energy and leadership of the group overseeing the Christchurch infrastructure rebuild, on top of his day job as chief executive of Watercare Services.
This criticism underestimates the energy and intelligence of the man.
I met an old mate at Napier Airport a week or two ago.
She was assisting a delegation from Internal Affairs investigating local body amalgamation in Hawke's Bay.
It looks like Len and Mark have been so successful the Auckland experience is catching.
