Four New Zealand rowing crews have the chance to supercharge the country's slow start in day six action at the Paris Olympics.

Both double sculls duos and both coxless four combinations contest their respective finals from 9pm tonight.

Former Olympic rower Eric Murray says Brooke Francis and Lucy Spoors are likely to bring home a gold medal for women's rowing.

"Going off paper, they are the fastest qualifiers - and I think they're finding themselves in a position they wouldn't have expected."
