What are sub stocks?

Sub stocks exist due to industry and Fisheries NZ agreements to divide the ACE within a quota management area; this creates a catch limit for each sub-area. These agreements have been put in place to spatially manage fisheries extractions at a finer level than is currently possible under regulations. They have been in place for decades for some stocks and have proven a successful tool in place of splitting a QMA under the Fisheries Act.

Sub-stocks are important to ensure long term sustainability of the specific fisheries and also serve as a demonstration of leadership by industry. The following stocks have sub-area split agreements in place:

  • Hoki – HOK1E & HOK1W
  • Orange roughy – ORH2AN & ORH2AS
  • Orange roughy – ORH3BES, ORH3BNW, ORH3BP & ORH3BSA
  • Oreos - OEO4B & OEO4S
  • Tarakihi – TAR1E & TAR1WTAR7E & TAR7W
  • Orange roughy (ORH1A, C, B, D, MC) Oreos (OEO1S, OEO3AB, AS) are managed at a catch level only, with no sub stock ACE being allocated.

Managing Sub Stocks

At the start of the fishing year, ACE with a sub stock agreement will be split according to the percentage split of the TACC for that QMA. This is done by a process of Government direction/guidance and shareholder agreement.

Our system monitors ACE transfers and electronic reports for sub stocks. When these are received, they become available under the SRE tab for completion or adjustment. You can adjust sub stock catch splits at any time during or after a fishing trip.

Sub Stock Details During an ACE Transfer

1 If your ACE transfer includes stocks requiring sub stock splits (e.g. HOK1, TAR1), you can split the amount at the time of transfer.
This method will split the amount according to industry splits (the default split ratio), defined by the sector representative entity.
Note: The default split ratio may change from fishing year to fishing year. 
2 To split the amount at the time of transfer, check the Use Industry Splits checkbox.
Complete your ACE transfer as normal and the system will split the stock according to the default split ratio.
Note: If you transfer all your ACE for a stock that requires sub stock splits, the system will automatically split it for you.

Sub Stock Transfers

1 Using the menu on the left-hand side, click Sub Stock Transfers to open the section.

2 The Sub Stock Transfers screen will display.
Here you can view a list of all sub stock related ACE transfers and ACE allocations for a given fishing year.
In addition, this screen will display any transfers with outstanding splits where you can specify the split amounts yourself.

3 Use the filters to help narrow your search. You can filter by:
  • Stock code
  • Fishing year
  • Other party
  • Status

4 To provide splits for an ACE transfer, click Complete Splits next to the transfer.
Two fields will appear where you can enter the split amounts
The sum of the split amounts must equal the total amount of ACE transferred. 
Ensure you've entered the correct splits and click Save to complete. Once the splits have been saved, they cannot be changed. 
Note: You can only specify the split amounts if you were the transferor/seller of the ACE.
You cannot specify the splits if you bought the ACE from another permit holder.

Trip Catches

1 Using the menu on the left-hand side, click Trip Catches to open the section.

2 The Trip Catches screen will display where you can view sub stock data from your fishing trips.
Trip Catches are calculated from electronic reports, and the split amount is based on the amount of fishing activity in each sub area. 
The system aggregates amounts from all catch, landing and disposal reports/events within a trip. 
In other words, if 60% of your fishing happens in HOK1 or TAR1 West and 40% in East, the system will split the total catch 60% West and 40% East.

3 You can override the system calculated splits at any time, but we recommend doing this only when necessary.
To do this, click Update Splits on the corresponding trip row and enter the corrected amounts.
Note: If you update the split amount(s) yourself, that amount will stay as is. If any reports from that trip are amended later, such as a landing report, the split amount won't reflect the change(s). We suggest you only update splits when necessary and after you have entered confirmed greenweights in corresponding landing reports.
