All Blacks scoring on the rugby field may lead to the public scoring off it, with a mini baby-boom possible if New Zealand beats France in the Rugby World Cup final.
The last and only time the All Blacks lifted the William Webb Ellis Cup, in June 1987, there was a brief baby boom nine months later.
Figures released to the Otago Daily Times from Statistics NZ show that during March 1988 there were 4822 births, almost 400 births than in February and April.
All other RWC tournaments, barring the 2003 RWC, resulted in an increase in births nine months later when compared with the previous month.
The All Blacks lost to arch-rival Australia 22-10 at the 2003 tournament.
