Steve Hansen has calmed fears about Richie Mo'unga, the All Blacks' latest injury worry.

The first-five was sidelined after going down with a shoulder issue in the 58th minute of the All Blacks' 36-0 Bledisloe Cup win over the Wallabies at Eden Park.

Asked about Mo'unga, who left the field in the second half after getting hit in a strong tackle by Wallabies No 6 Lukhan Salakaia-Loto, Hansen said: "The doc says he has a sore shoulder, but we'll know more in the morning."

Mo'unga was influential for the much-improved All Blacks, scoring the first try of the game, while kicking over three conversions and a penalty (missing one).

The severity of Mo'unga's injury is still unknown but Hansen was confident about the 25-year-old's World Cup prospects.

Asked if he had any fears over Mo'unga's involvement in Japan, Hansen said: "No."

Just last week, centre Jack Goodhue left the field with an upper leg injury in the opening quarter in Perth.

Meanwhile, Brodie Retallick is still recovering after suffering a shoulder dislocation against South Africa last month.
