1. North Waitemata Harbour
The drawback of boating - and people - traffic so close to town is countered by ease of access to the wharves and rocky headlands on Waitemata. Birkenhead or Northcote Pt wharves are popular spots (the ferries aren't too frequent on weekends), or the rocks below the Chelsea Sugar refinery.
2. City side
Insiders love the long stretch of the Herne Bay wharf (handy to cafes for consolation or celebration afterwards) or the promenades under the Harbour Bridge. To the east, try the 100m-long Orakei wharf, the Tamaki Drive wall, where baitfish can sometimes be seen being chased by kingfish, or the rocks around Tamaki Yacht Club.
