The Nerf Rebelle Agent Bow is popular with girls. It has a recommended retail price of $54.99 and launches arrows at targets up to 20m away. For boys, the $79.99 Nerf Mega Thunder Bow loads five darts in the front and is another Christmas winner.
"Although these products are not connected with the Hunger Games films, the movies have inspired a lot of interest in them," Gray said. "The toys have a natural bow action feel to them, which kids love. Both of these items are doing really well for us and will be top festive sellers."
Other more traditional toys and games are holding up well against high-tech competition.
Hasbro's Simon Swipe ($44.99) involves players keeping up with a randomly changing sequence of coloured lights. A revamped version of vintage board game Monopoly ($44.99) is also popular.
"Reinventions of classic genres have been making a comeback," Gray said. "Simply refreshing a game like Monopoly can spark the interest of a whole new generation of kids.
"Despite a lot of new technology being available, kids and adults still like something that is not too expensive to buy or too complicated to play or operate."
Another trend this year is a resurgence in traditional action-hero figures, Gray said. Kiwi doll My Magical Mermaid is also doing well - as is anything connected with the animated movie smash hit =Frozen.
Gray gets to see what toys, games and gadgets will be popular at Christmas almost a year in advance.
Next month he will travel to a huge toy fair in Hong Kong where the toys set to be next year's must-have presents will be on show.
"There is an element of crystal ball-gazing when trying to predict what will be popular with kids," he added. "However, next year big movies will include further instalments of Jurassic Park, Star Wars and The Avengers so it is almost certain that any merchandising connected with those will be very hot indeed."
