There seems to be some evidence that having a longer duration between the first and second doses provides better long-term protection, i.e. gaps of 7+ weeks, compared to the 3+ weeks the US and Israel have generally done.
NZ is currently thinking about increasing the gap to > 6 weeks because of this.

I wonder how much that would affect things.
