The skaters will learn skills and develop team strategies.
As the sport grows in this country with an interesting sub-culture of women, many of whom have no other sports background, the seminars will also teach them how to foster their clubs and run them like a self-sustaining business.
Scrimmages will be held daily from 7pm-9pm, with a final game played at the end of the seminars.
McGhie said the guests would contribute to Wanganui, planning to hold movie nights and relax at the Splash Centre, cooling sore muscles.
To promote the event, the club also hope to organise a "Running of the Bulls" on Victoria St. A group of "volunteer" men, dressed in white with red bandannas and scarves, will run for it as the girls skate after them in red shirts with "soft" weapons.
"We don't harm them, we try and grab the bandannas and scarves," McGhie said.
The club are negotiating with Mainstreet Wanganui about the event.
The Rollers' last hit-out was a club game at home against Levin's Whenua Fatales in December, a 133-129 win.
