The Ohau Channel and Kaituna River page exists because this short corridor changes rules faster than a broad Rotorua Lakes page can explain. The current Eastern regulations split the water from the Lake Rotorua Outlet weir, through the Ohau Channel to Lake Rotoiti, then downstream of the Kaituna control gates and State Highway 2 bridge.
This page is narrower than Lake Rotoiti. Rotoiti covers the main lake and winter shoreline. This page handles the L3 action that causes mistakes: first decide whether the cast is in the first 200 m of Ohau Channel, the rest of the channel, Kaituna below the control gates, or Kaituna below SH2.
Ohau Channel And Kaituna Rule Path
| Planning layer | Ohau/Kaituna decision |
|---|---|
| L1 authority | Fish & Game New Zealand, Eastern region |
| L2 water | Ohau Channel from Lake Rotorua Outlet weir to Lake Rotoiti, then Kaituna River |
| L3 action | Match the exact section before deciding method, bag, anchoring, bait, or buying |
Do not use a Lake Rotorua, Lake Rotoiti, or lower Kaituna row as a shortcut for the whole corridor.
Current Ohau Channel And Kaituna Rows
As checked against the Fish & Game Eastern 2025/26 regulations on 5 August 2026, these are the controlling rows.
| Water or section | Season | Methods | Daily bag | Size and notes |
|---|---|---|---|---|
| Ohau Channel, Lake Rotorua Outlet weir to landmark about 200 m downstream of the weir | 1 Oct-30 Jun | Fly only | 8 trout | 350 mm minimum through Note 7; Notes 2, 5, 6, 7, 8 |
| Ohau Channel, from that landmark downstream of the weir to the Lake Rotoiti confluence | 1 Oct-30 Jun | Fly and spin | 8 trout | 350 mm minimum through Note 7; Notes 2, 5, 6, 7, 8 |
| Kaituna River downstream of the control gates | All year | Fly and spin | 2 trout | Notes 2, 6, 7 |
| Kaituna River downstream of the State Highway 2 bridge | All year | Fly, spin, bait | No limit | Notes 2, 3, 6, 7 |
The SH2 bait/no-limit row should not be moved upstream to the control gates, Lake Rotoiti, or the Ohau Channel.
First 200 M, Downstream Channel, Or Kaituna
The first 200 m below the Lake Rotorua Outlet weir is the sharpest method trap: fly only. From the landmark about 200 m downstream to the Lake Rotoiti confluence, the method changes to fly and spin. Both Ohau rows are 1 October to 30 June, not all year.
| Planned position | Better rule action |
|---|---|
| Lake Rotorua Outlet weir to the first landmark | Treat it as fly-only Ohau Channel water |
| Landmark about 200 m downstream to Rotoiti | Treat it as the downstream Ohau fly-and-spin row |
| Lake Rotoiti main lake | Use the Lake Rotoiti guide |
| Kaituna below control gates | Use the all-year fly-and-spin, two-trout row |
| Kaituna below SH2 bridge | Use the all-year FSB, no-limit row |
This is why buying and rigging should wait until the exact position is known.
Notes, Anchoring, And Bait
Note 5 says no trout fishing from an unanchored boat within 200 m of a landmark. The Eastern PDF also notes that boats are not permitted under Bay of Plenty Regional Navigation Safety Bylaws to anchor in the Ohau Channel. Keep the fishing row and boat-position wording together before planning a channel session.
| Note | Ohau/Kaituna planning effect |
|---|---|
| 2 | Set rods require boat fishing; scented artificial lures are not for fly-only waters |
| 3 | Bait-water bait movement rule applies where the row lists bait |
| 5 | Check landmark and Ohau Channel anchoring wording |
| 6 | No sports-fish fishing between 12:00 am and 5:00 am |
| 7 | Rotorua Lakes and inflowing tributary streams have a 350 mm minimum size |
| 8 | On Ohau's eight-trout rows, no more than two brown trout may be taken |
The rule source checked here is the 2025/26 booklet. Reopen the next Eastern notice before relying on these rows after 30 September 2026.
Licence And Buying Actions
Buy after the exact section is known. The authority remains Fish & Game Eastern for these freshwater rows, but the method and daily bag are not the same across the corridor.
| Buyer situation | Safer path |
|---|---|
| Ohau Channel only | Confirm first-200 m or downstream channel row before choosing method and licence |
| Kaituna below control gates | Confirm all-year fly-and-spin, two-trout row |
| Kaituna below SH2 | Confirm FSB and no-limit row; do not move it upstream |
| Non-resident visitor | Check Fish & Game non-resident options before buying |
| Ohau/Kaituna plus Taupo or Rotoaira | Fish & Game for this corridor; DOC Taupo or DOC Rotoaira for those separate waters |
| Ohau/Kaituna plus coast | Fish & Game for freshwater; MPI marine rules for the coastal catch |
A Fish & Game licence does not settle boat access, navigation safety, local signs, flow, land access, or clean-gear movement between lakes and rivers.
Before Fishing Ohau Channel Or Kaituna River
- Confirm the exact section: first 200 m of Ohau, downstream Ohau, Kaituna below control gates, or Kaituna below SH2.
- Open the current Eastern regulations and match that row.
- Confirm season, methods, daily bag, size note if attached, brown-trout cap if attached, bait status, and fishing hours.
- Check landmark, unanchored-boat, and Ohau Channel anchoring wording before a boat session.
- Choose the correct Fish & Game product for resident or non-resident status and trip duration.
- Clean and dry gear before moving between Lake Rotorua, Ohau Channel, Lake Rotoiti, Kaituna River, Taupo, or the coast.
The Ohau Channel and Kaituna River are ready for a purchase decision only when the weir, 200 m landmark, Lake Rotoiti confluence, control gates, and SH2 bridge have been separated into the row that actually controls the cast.
FAQ
Do I need a Fish & Game licence for the Ohau Channel or Kaituna River?
Yes. These rows sit in the Eastern Fish & Game freshwater sports-fishing path. Buy after matching the exact channel or river section.
Is the Ohau Channel the same rule as Lake Rotoiti?
No. Lake Rotoiti has its own page and rows. The Ohau Channel has a first-200 m fly-only row and a downstream fly-and-spin row to the Lake Rotoiti confluence.
Can I use bait in the Ohau Channel?
No Ohau Channel row lists bait. Bait appears only in the Kaituna River row downstream of the State Highway 2 bridge.
What is the Ohau/Kaituna rule trap?
The method and bag change quickly: fly-only first 200 m below the Lake Rotorua Outlet weir, fly-and-spin below that to Lake Rotoiti, two-trout bag below control gates, and no-limit FSB only downstream of SH2.
