McCullum has just finished his stint in the Pakistan SuperLeague, having also played for Brisbane in the Big Bash and will next month turn out in the Indian Premier League.

McCullum, who made six appearances for Middlesex last season, will re-join in early July and be available for nine of their group matches.

He'll again join up with former team-mate Daniell Vettori, who has been brought in as Middlesex's special T20 coach.

Vettori and McCullum worked together at the Brisbane Heat this summer.

Derbyshire have hired former New Zealand player and coach John Wright for the T20 season.

Middlesex's managing director of cricket, Angus Fraser, said: "We are naturally delighted to have Brendon back to play for Middlesex in this season's NatWest T20 Blast.

"Brendon had a hugely positive influence on the club in 2016 and I'm sure he will have a similar impact this summer."

Middlesex's improved Twenty20 form last season saw them reach the quarter-final before going down to Northants.

McCullum is also set to return to the Caribbean Premier League later this year with the Trinidada Knight Riders.

The CPL will holds its auction this week with 17 New Zealanders taking part including Corey Anderson, Colin de Grandhomme, Grant Elliott, Jimmy Neesham, Ish Sodhi and Jesse Ryder.
