The Southern Steel coach has been named as head coach for the New Zealand All Stars team to play at this month's international series in Auckland.
Made up of players that did not make the Silver Ferns, the side will play the Fiji Pearls, New Zealand men and the Ferns from June 27 to 29.
Bloxham will be joined by Central Pulse coach Yvette McCausland-Durie, who will be her assistant.
Meanwhile former Silver Ferns coach Yvonne Willering will mentor the pair.
The experience comes after Bloxham joined the Silver Ferns for last year's Constellation Cup in Australia.
In three years of head coaching at the ANZ Premiership level, she has helped the Steel to two titles and reached this year's elimination final.
Netball New Zealand head of high performance Keir Hansen said the appointment of Bloxham and McCausland-Durie highlighted another development opportunity for the country's's leading coaches.
"It is important that we continue to promote the coaching pathway for Kiwi coaches and support their professional development," Hansen said.
"Both Reinga and Yvette have the chance to work with elite athletes against international opposition which brings different challenges.
"To be working alongside someone with the netball knowledge of Yvonne Willering, who has coached around the world, is a valuable insight for our franchise coaches."
