Tāhunanui Beach Fishing: Back Beach Surfcasting in Nelson

Last updated October 2026

Tāhunanui Beach is Nelson’s closest beach, a 1.75 km stretch of sand about five minutes’ drive from the city. Its western end, which locals call the Back Beach or dog beach, is where people go surfcasting and kitesurfing, away from the swimmers on the main beach. Here the beach ends in a sandy spit beside the deep Blind Channel. Fishing is not allowed inside the swimming zone marked by black buoys on the main beach.

What Makes It Worth the Trip

Tāhunanui is Nelson’s main city beach, with a long stretch of sand backed by dunes, playgrounds, sports fields and a holiday park. On fine summer days it is busy with swimmers, paddle boarders, kayakers and kitesurfers, and the eastern end has rock pools at low tide.

The western end is different. The beach runs out into a sandy spit with dunes and low trees, reached by Back Beach Road, and very wide tidal sand flats lie inside it.

At low tide you can walk a long way out on the spit. The deep, dark-green Blind Channel runs close past the outer edge of the flats on the seaward side.

This Back Beach is Nelson’s off-lead dog beach. It is also popular for kitesurfing, and because strong currents keep most swimmers away, it is the better place to fish. The estuary behind it is wildlife habitat that Nelson City Council rates as of outstanding value.

How to Fish Tāhunanui Beach

Where to stand

Head to the Back Beach at the western end and fish from the sand along the spit, where the deep Blind Channel runs close to the edge of the flats. Watch the tide: the flats inside the spit are very wide and cover as the tide comes in, so keep an eye on your way back.

You can also fish other parts of the main beach as long as you do not get in the way of swimmers, but never inside the area marked by the three black buoys, which is for swimming only. On a busy summer day the Back Beach is the better choice.

When and what to use

Moving water around the tide changes usually fishes better than slack water, and early mornings avoid the summer crowds. Take a surfcasting rod, sinkers heavy enough to hold in the current, fresh bait and a few metal lures, and ask at a Nelson tackle shop what has been caught off the beach recently. For deeper water at the harbour entrance, see our Boulder Bank fishing guide.

Getting There and Facilities

• Road: Tāhunanui is about five minutes from central Nelson and five minutes from the airport. For the Back Beach, follow Back Beach Road to the western end.
• Parking: free.
• Bike: the beach is a short detour from the Great Taste Trail, about 3 km from Nelson Airport.
• Food and coffee: the Beach Café sits behind the dunes, and there are cafés along Rocks Road.
• Dogs: the Back Beach is the place for off-lead dog exercise. Dogs are banned from the main beach, playgrounds, sports fields and public buildings.
• Family: playgrounds and sports fields behind the main beach make it easy to bring the family.

Rules and Safety

• No licence: sea fishing needs no licence, but MPI’s Challenger area size limits, daily limits and closures apply.
• Swimming zone: fishing is not allowed between the black buoys on the main beach. Elsewhere, keep lines and hooks well away from swimmers. Council has had complaints about swimmers being caught up in fishing lines.
• Kitesurfers: kite boarders launch past the third buoy, and the Back Beach end is popular for kitesurfing. Keep your lines clear of them.
• Currents: the Back Beach has strong currents, which is why swimmers avoid it. Do not wade out into the channel.
• Tidal flats: the incoming tide covers the wide flats inside the spit. Do not get cut off.
• Water quality: sewage has overflowed into the Waimea Inlet after heavy rain in the past, and the council has closed the beach to swimmers as a precaution. Avoid the water and do not gather shellfish for a few days after heavy rain, and check MPI’s biotoxin alerts before gathering shellfish at any time.
• Scallops: Tasman Bay is closed to scallop fishing until further notice.
