The winner is the team who can throw and catch a raw egg over the greatest distance.
The team starts off 10 metres apart. After each throw the pair moves further apart at 10 metres a time.
The eggs are being supplied by Kairanga Eggs in Taihape this year, she said.
Gumboot Day was all about a taste of life in a small Kiwi town and it's never, ever boring, she said.
Gumboot plank racing is a huge hit with two planks laid side-by-side, and two pairs of gumboots on each plank, so it needs four competitors to get the gummies on and stride it out.
But it's tossing the gumboot which most people head to Taihape for, she said.
"Most entrants will be hoping their throw will get them into the North Island gumboot-throwing champs at 2pm.
"It's our Taihape day and we're very proud of it" she said.
