With the retirement of Paula Bennett, National Party leader Todd Muller is announcing a caucas reshuffle.

"Today I am confirming a minor shadow cabinet reshuffle," says the Bay of Plenty-based MP.

Dr Shane Reti will be ranked number 13 and will take on Associate Drug Reform.

Muller says Reti has demonstrated a huge intellect and capacity for work, supporting Michael Woodhouse in our COVID-19 response, as well as achieving much in the Tertiary Education portfolio.

Simon Bridges will be picking up the Foreign Affairs portfolio and will be ranked at number 17.

"Simon has been leader and a minister for a number of years in the last National Government. He expressed a desire for this portfolio and his experience will be valuable in this important role."

Deputy Leader Nikki Kaye will pick up the portfolio of Women and will make several announcements associated with this portfolio in the coming months.

Amy Adams will take the portfolio of Drug Reform.

"She will work with Shane Reti in this area," says Muller.

"This reshuffle will ensure that National has a strong team, with huge depth, that will deliver more jobs for New Zealand."
