"What goes on in your head is the biggest challenge with a class like this," she said. "I practice de-stressing myself before big classes."
Trained by her brother Logan Massie, Massie, said she was hugely grateful for the support of her family when it comes to chasing her equestrian dreams.
Five-time series winner Laurie has her stunning grey stallion Dunstan Casebrooke Lomond and Dunstan On The Point Eve entered.
Her preparation for the opening round has been meticulous and meant she travelled about 1450km back and forth between Gisborne and Mystery Creek last weekend to ensure Lomond had a good run in an arena similar to the Hawke's Bay grounds.
Eve had her lead-up at Foxton, a little earlier and Laurie is confident both will head into the class primed and ready.
Laurie, who won the series last year, is New Zealand's best-performed finisher at the World Cup final with her sixth equal in Sweden in 2011 aboard Dunstan Delphi.
Taupo's Helen McNaught-McFarlane and her quirky grey Carnutelabryere have been the combination to go head-to-head with Laurie over the past two seasons, and in the 2015-2016 season won the final but placed second in the series.
"The World Cup series is certainly our priority for the season," McNaught-McFarlane said.
"Roger Laplanche is a great course builder and while I am not expecting to push everyone too hard for the opening round, I am sure it will be strong enough."
Carnutelabryere has come back into work well for the new season.
"He is looking the best ever I think and has come out looking fantastic."
Beatson, who represented New Zealand in a World Cup final previously, has two on the card with Conyers and Schimmel Warrior, both of whom have plenty of mileage at top level.
Conyers was actually brought to New Zealand as a 4-year-old dressage horse, but his father Concorde's jumping lines proved too strong and he made the switch.
Wilson brings McMillans Midway Smooth Dude out for his first World Cup start.
"I am happy with him at the moment but you never know how things are going to go when you move up another level," Wilson said. "It is a big test that next step and will be a tough ask."
Also entered are Samantha Morrison (Tauranga) aboard Biarritz, husband and wife Brooke and Oliver Edgecombe (Waipukurau) on LT Holst Aunty Annette and Ultra Blue NZPH respectively, Lily Tootill (Auckland) and Ulysses NZPH, Rachel Malcolm (Cambridge) on Equador MVNZ, Daniel Blundell (Ocean Beach) on Lavello, Mathew Dickey (Oakura) on Quango, Tess Clark (Auckland) on Sinatra II, Sam Peters (Whangarei) on Zabambi and Lucy Fell (Opiki) on Tinapai.
The New Zealand league runs over six rounds, with the best four to count for each rider.
Following Hawke's Bay, the next two rounds will be held indoors, at Mystery Creek (November 4-6), followed by Feilding (December 2-3). Competition then moves back outdoors for Taupo (December 15-17) and Dannevirke (January 6-8) with the grand final at Waitemata (January 14-15).
The winner of the New Zealand league has the opportunity to represent the country at the Longines FEI World Cup Jumping 2015/2016 final which is being held in Omaha, Nebraska, in the United States, from March 29-April 1, 2017.
