The last time I was in Lyttelton there were 2 coffee carts so that blows you out of the water. What I find interesting is Chch has 3 yacht chandleries- same as Auckland has/had.
170 you say. Don't know how many in Chch but enough to support 3 chandleries. The boats all around the harbour ie Cass,Purau,Corsiair, would never prefer to shop at the marina instead of going thru to Chch.? What does your bullshit marketing diploma think of that?
