(1) Rates of the levy for later levy years are to be fixed by BBNZ by any means by which it can lawfully make such decisions.
(2) BBNZ may not fix a particular rate for a levy year unless either—
(a) the rate is no greater than the corresponding rate for the previous levy year; or
(b) the rate was approved by growers at the most recent annual general meeting of BBNZ and either—
(i) is proportionately greater than the corresponding rate for the previous levy year by no more than the annual percentage increase in the Consumers Price Index most recently released before that meeting; or
(ii) was later approved by the Minister of Agriculture.
(3) For any levy year for which a particular levy rate is not fixed by BBNZ, the corresponding levy rate for the previous levy year will be the rate that applies.
