All Blacks wing Will Jordan scored a hat-trick to become New Zealand's record try-scorer during their Nations Championship Test against Italy.

Will Jordan scored a spectacular hat-trick to become New Zealand's outright record try-scorer as Italy were overwhelmed 47-17 in a fast-paced Nations Championship Test on Saturday.

The All Blacks shook off an unconvincing opening period to run in seven tries, securing two wins from two in the inaugural 12-nation competition under head coach Dave Rennie, following their 34-32 defeat of France last weekend.

The home side led 14-10 after a sluggish first half but ignited in the third quarter of the match, crossing the whitewash four times after Italy were reduced to 14 players.

Two of those scores went to the clinical Jordan, lifting his career international tally to 50 in 56 Tests — pulling him one clear of the previous record-holder, former winger Doug Howlett.
