Building a third Viaduct Basin to accommodate a growing fleet of fishing boats and yachts is among 40 projects included in the draft waterfront plan.
Extending the Halsey St Wharf further past the end of Princes Wharf is one of the bolder ideas to emerge in the 30-year plan being developed alongside the Auckland Plan and the city centre masterplan.
Another uncosted "aspirational" project is to create an island off Westhaven Marina, built from dredgings, around which people could live on boats.
Waterfront Auckland planning and design manager Rod Marler says the plan also contains a lot of less expensive "quick hits", such as spending $700,000 to tear up the bland paving at Waitemata Plaza and create a green space in the Viaduct Harbour.
The council body is also keen to get on with a walking and cycling boulevard from the Auckland Harbour Bridge to Teal Park and to extend the heritage tram circuit around the Wynyard Quarter to Britomart following overwhelming support from interested groups. In the longer-term trams could run up Queen St and 15km along the waterfront to St Heliers.
