"There's no easy games and managing injuries, staying fit and recovery between games becomes important, especially if you've got back-to-back games."
The Black Sticks are targeting the second-round match against Korea as a "must win" and also the first-round clash with Germany as the other game vital to their top-four hopes. Their other pool B match is against the highly ranked Dutch.
All five teams who played the 1978 inaugural Champions Trophy - or Super World Cup as it started out - will be in Auckland.
That first tournament, won in Lahore by hosts Pakistan, brought together Australia, Great Britain, New Zealand and Spain, who finished in that order.
After a five-team tournament in 1978 and seven in 1980, six teams contested the Champions Trophy from 1981 to the present day, apart from 1987 and 2007, when eight teams played.
New Zealand have played in five Champions Trophies, finishing fourth of the five teams in 1978, fifth in 1984 and sixth (last) in 1983, 2004 and last year. Australia have been the most successful team, winning 12 times. The Netherlands have won eight, as have Germany (including the former West Germany).
Hayward said a top-four finish would show they were on track for the Olympics. Anything less would shine a light on their shortcomings.
"Everything we do now is geared towards London and it's the same for all teams here - finding out about the opposition and learning a lot about ourselves, because July and August next year is what it all counts for.
"We're definitely capable of pushing for a medal, and a lot of older guys in our squad have been to two Olympics already and aren't going just to participate - they want to go and medal ... Beating Aussie [at the Oceania Cup] has given us some confidence but there's still things to work on that other teams have exploited. The next week is a peg in the ground to where we sit."
His parents, grandparents and brothers will head to Albany to watch him play and he's hoping to reward them with a goal or two as one of the Black Sticks' specialist penalty corner drag-flickers, with Matt L'Huillier the other.
Hayward said they'd decide on the spot who would step up to flick. With both playing in defence they were often not on the field at the same time.
"If we're both on there's a call made or there might be a special variation we do. At this level it's as much about keeping teams guessing because PCs are such an important part off the game."
