A year after coaching the team with Margaret Davies, Roberts will co-coach the team with Masterton's Ian Monaghan this time round.
Both the women's and men's development teams are made up of three under-25 players and two under-18 players.
The full New Zealand squad, including the senior Black Jacks, will go into camp on March 15 ahead of the three tests on March 18, 19 and 20.
Last year, Roberts and Davies guided the women's team to a series win against Australia, but the men fell short.
''This is my second run at it,'' Roberts said.
''This year I'm hopeful that we can go up there and take both the men's and women's series.''
As well as playing for the North East Valley Bowling Club and coaching the national development team, Roberts is a coach and selector for the Dunedin development team, and a co-coach of the South Island team.
He and Monaghan are both part of the Sport New Zealand Performance Coach Advance programme, which launched last April to improve the quality of coaching provided to pre-elite emerging athletes.
Roberts, who praised the coaching course, is one of 12 Otago coaches in the programme, which Mike Weddell, from Sport Otago, leads.
While the first year of the programme is in its final few months, the coaches will be encouraged to stay involved into the programme's second year, when another 12 coaches are selected.
''As we finish up the first year, we do a professional development plan so they continue to learn afterwards,'' Weddell said.
''It's not just a course where you get a certificate and that's it. It's a long-term programme for them.''
During the course of the year, eight seminars were held where speakers, including Kiwis coach Stephen Kearney and former New Zealand cricketer John F. Reid, shared their knowledge with the 12 Otago coaches.
''It's been really good,'' Weddell said.
''There are some outstanding coaches.
''Some of them are more engaged than others, but it's not because they aren't interested, it's because their coaching load is quite high.
''Feedback from the coaches has been really good. They have got a lot out of it.''
A new intake of coaches for the second year of the programme will be selected in early April.
The national programme is being delivered in six regions and in total 102 coaches are on board.
