"I won every race after that and so, in the end, it was pretty straight-forward."
Elwin's November victory in Te Awamutu for the women's motocross crown was only her first national title, but since that time she has been going from strength to strength after two seasons racing competitively.
"I'm a lot fitter now that in the past and this meant I could maintain my pace for longer," she explained.
"I think it was easier to defend the title this year that it was to win it for the first time last season.
"Of course I'll be back with my Yamaha YZ125 to defend my title again next year, although we'll be racing at an entirely new venue and nobody knows yet what that will be like."
Next on the horizon for Elwin is to contest the big annual Labour Weekend Motocross Extravaganza at Taupo and then she is considering teaming up with Taupo's Ashley Bond to race the annual Acerbis Four-hour endurance race near Taupo on November 1.
