Dr SHANE RETI (National—Whangarei): Thank you, Madam Chair. I'd like to speak to the enablement date of this bill. In this contribution, I'd like to raise several points. I'd like to suggest that, at a minimum, the first enablement date be the end of 2020, and I'll make the arguments for that, and, in the second instance, the end of 2022 may be even more suitable.
