Nelson has a very wide range of and a large number of accommodation options. There is something to suit all budgets and expectations.
There are many websites listing accommodation options. Be careful to check the detailed addresses, some site search functions will bring up accommodation in Motueka or Golden Bay as well as Nelson. Most sites bring up only accommodation providers who have “listed” with the site, so try several.
