"Last year my girlfriend was ready to have our first baby and the meeting didn't go how I wanted it," said Holder. "I got back to Europe and met my little fella and the season just got better and better.
"The track here is awesome and I'm looking forward to having a better night. I want a good result so I don't have to talk about that old one.
"It's tough these days and hard to stay in the 16 [only 16 riders contest the world series] and you need to get a good start to the season. If you drop out of the top eight you have to qualify all over again to get back in. There's so much talent out there now you have to be on your game all the time."
Someone who knows a thing or two about solo speedway, and New Zealand, is three-time former champion Ole Olsen and long-time combatant of Kiwi legend Ivan Mauger. Olsen is now the FIM speedway director of sports and loves coming back to New Zealand.
"I'm very pleased and thrilled about being able to come back to Western Springs after the success of last year," said Olsen. "Until last year, it had been a long time since I was racing here [1970s and 80s]. The track is still very similar but we have to put a new surface on it for the bikes."
New Zealand has only one rider competing at the elite level in Europe, Ricky Wells, who rides for the UK's Sheffield club and was the US under-21 champion in 2007 and 2008 and the AMA champion in 2009.
"I can remember racing in Gisborne, Napier and Templeton. Western Springs has a great history in the sport and to get more Kiwi youngsters to get into the sport they need to open all those tracks up and get going again," said Olsen. "You'll then get a lot more riders doing well like you did in the 1960s and 70s."
