In each instance, Monaghan will be offering advice to some of the country's most promising players.
The women's and men's development teams are made up of three under-25 players and two under-18 players while the North Island team is part of a talent identification programme for future Black Jacks.
Monaghan sees his latest appointments as providing a royal opportunity to prove he is capable of taking the "next step up" on the coaching front.
"I guess it's all part of the learning curve. It's going to be a good challenge," he said.
Meanwhile on the Wairarapa bowling scene, it was Fiona Mancer from the Masterton club who won Bowls Wairarapa's open women's singles title finalised at the Masterton greens last Sunday.
And when Mancer, a fourth-year bowler who just happens to be coached by none other than Monaghan, beat Featherston's Dale Batty 21-11 in the decider it meant she had completed a clean sweep of the centre's open titles for the 2014-15 season, having already taken out the pairs with Judith Wyeth, the triples with Wyeth and Dorothy Christensen and the fours with Wyeth, Joy Gibbs and Christensen.
Mancer, who had not tasted success at centre level before this season, has been named as singles player in the Wairarapa senior women's squad but, while she is pleased to be given that opportunity, she says she prefers to play pairs or triples.
"I keep getting told I should focus on singles so that's where I play. I'm just happy to go wherever they want me," she said.
It was an all-Masterton affair in the final of the plate on Sunday with Brenda Whitehead beating Dorothy Christensen.
