"(1) ... no person shall – (a) Import into or export from New Zealand any controlled drug, other than a controlled drug specified or described in Part VI of the Third Schedule to this Act; or (b) Produce or manufacture any controlled drug; or (c) Supply or administer, or offer to supply or administer, any Class A controlled drug or Class B controlled drug to any other person, or otherwise deal in any such controlled drug; or (d) Supply or administer, or offer to supply or administer, any Class C controlled drug to a person under 18 years of age; or (e) Sell, or offer to sell, any Class C controlled drug to a person of or over 18 years of age; or (f) Have any controlled drug in his possession for any of the purposes set out in paragraphs (c), (d), or (e) of this subsection. (2) Every person who contravenes subsection (1) of this section commits an offence against this Act and is liable on conviction on indictment to – (a) Imprisonment for life where a Class A controlled drug was the controlled drug or one of the controlled drugs in relation to which the offence was committed: (b) Imprisonment for a term not exceeding 14 years where paragraph (a) of this subsection does not apply but a Class B controlled drug was the controlled drug or one of the controlled drugs in relation to which the offence was committed: (c) Imprisonment for a term not exceeding 8 years in any other case. (2A) Every person who conspires with any other person to commit an offence against subsection (1) of this section commits an offence against this Act and is liable on conviction on indictment to imprisonment for a term – (a) Not exceeding 14 years where a Class A controlled drug was the controlled drug or one of the controlled drugs in relation to which the offence was committed: (b) Not exceeding 10 years where paragraph (a) of this subsection does not apply but a Class B controlled drug was the controlled drug or one of the controlled drugs in relation to which the offence was committed: (c) Not exceeding 7 years in any other case."
"Where a person is tried on an indictment alleging alternative counts of conspiring to import a Class A controlled drug or conspiring to import a Class B controlled drug, and where there is evidence which, if accepted, would prove beyond reasonable doubt that the person has conspired to import either a Class A controlled drug or a Class B controlled drug but the evidence is insufficient to prove which class, may that person properly be convicted on either count in the indictment?"
"[21.] ... subs (2A) contemplates that the first inquiry is whether para (a) is satisfied. That is so ‘where a Class A controlled drug was the controlled drug or one of the controlled drugs in relation to which the offence was committed’. If the answer is No, the next inquiry is under para (b), that is ‘where paragraph (a) of this subsection does not apply but a Class B controlled drug was the controlled drug or one of the controlled drugs in relation to which the offence was committed’. If that answer is also in the negative, the next step is to go to para (c), which makes the penalty ‘Not exceeding 7 years in any other case’. [22.] On that analysis subs (2A) provides a comprehensive statement of liability for conspiracy offending in relation to controlled drugs. It is complete in its coverage because of the successive and exhaustive steps which may be required. The answer to (a) will be in the negative where it is not proved beyond reasonable doubt that a Class A controlled drug was a controlled drug ‘in relation to which the offence was committed’. That language and its employment in that context is necessarily directed to proof that the offence was committed and there is no justification for reading ‘was’ in any lesser sense. Unless there is proof beyond reasonable doubt, (a) is not satisfied. It follows that, where there is uncertainty as to whether the drug, the subject of the conspiracy agreement, was a Class A controlled drug, that uncertainty may also preclude a positive answer to the inquiry under (b), even where there is other evidence that it was a Class B controlled drug. In that situation, and also where there is no affirmative evidence that it was a Class B controlled drug, para (c) on its face applies and the maximum penalty for the offending is seven years’ imprisonment. [23.] It is clear from the scheme and language of the offence – creating provisions of s6(2A) that the legislature imposed different maximum penalties depending on which one of paras (a), (b) or (c) applied. As well, it is clear from the structure of the subsection that it intended to cover the field, leaving no gaps. The more serious the offence in the eyes of the legislation – here the need to distinguish from the less serious drug – the higher the maximum penalty to which an offender is liable. Section 6(4A) applying ‘where any person is convicted of an offence relating to a Class A controlled drug or a Class B controlled drug against any of paragraphs (a), (b), (c), and (f) of subsection (1)’ also reflects that focus. And where it is not proved that the offending came within either of the more serious categories described in paras (a) and (b), para (c) is the residual provision which prescribes the lower maximum punishment for the offence which lacks those more serious features."
