"I am extremely excited to be reuniting with the Pakistan team as their mentor for the ICC Men's T20 World Cup in Australia and can't wait to join the culture again," Hayden said. "I have seen how Pakistan have been performing in the ACC T20 Asia Cup and Sunday's win over India was brilliant. I think this Pakistan side has got what it takes to excel in Australia and the conditions will suit them, both from a batting and bowling perspective.

"This team has all of its bases covered and I am sure it will light up the World Cup as it did in the UAE last year. I feel privileged to be allowed to pass on all my experience and knowledge about all conditions in Australia and can't wait to be back in the Pakistan dressing room."

Hayden will be working alongside his former Australian team-mate Shaun Tait, who is the current Pakistan bowling coach. Among Pakistan's coaching staff are head coach Saqlain Mushtaq and batting coach Mohammad Yusuf.

Hayden will join the team directly in Brisbane on October 15, following Pakistan's arrival from Christchurch after competing in the T20I series also involving Bangladesh and hosts New Zealand.

Saqlain will also be released from the role next year in February after he completes his one-year contract. His appointment was on an interim basis and was extended. He refused to have a long-term contract due to his commitments and has decided to part ways after New Zealand's tour to Pakistan next year in February.
