The All Whites striker Chris Wood set up the matchwinner as his English football club Leicester City won the second division Championship title, with a 1-0 away win at Bolton Wanderers.
That opened an unassailable seven-point lead at the top of the second tier, with two matches remaining.
Leicester has already secured a return to the Premier League for the first time since 2004 earlier this month.
Wood came on as a second-half substitute as the Foxes reached 96 points from 44 games, ahead of Burnley, who clinched an automatic promotion spot on Tuesday with a 2-0 victory over Wigan Athletic.
Leicester, owned by Thai businessman Vichai Srivaddhanaprabha, missed out on automatic promotion last season after winning two of their final 13 matches before being knocked out in the playoffs by Watford after Anthony Knockaert missed a last-minute penalty and City then conceded in a dramatic finish.
Reading moved back into the playoff places with a 2-0 home win over Middlesbrough thanks to an Adam Le Fondre strike and an own goal from George Friend.
