The buy-back cost for inshore fish stocks is estimated to be between $0.76 and $3.1 billion, with a mid-point of $1.67 billion. The New Zealand Institute of Economic Research tested a range of scenarios and the buy-back cost varies depending if shares in just the inshore fish stocks are redeemed or all of the inshore and off-shore stock shares are redeemed.

Modelling the buy-back cost of all fish stocks suggests the estimated buy-back cost will range between $1.27 billion and $5.28 billion, with a mid point of 2.75 billion.
