This year, Northland and North Harbour are competing as separate entities.
Northland played their best hockey in the second spell of the game against Harbour, holding their former teammates to a 1-1 draw after trailing 0-6 at the break.
The side are targeting the first crossover match tomorrow against the bottom team of pool B as their biggest test.
The Northland under-21 women have been much more competitive at the tournament so far. They lost their first game on Monday 1-3 to North Harbour, with an early loss of concentration costing them dearly.
They were two goals down in the first 10 minutes before finding some rhythm, with Chelsea Beasley reducing the deficit to a single goal by halftime.
The second spell was more even but Harbour were the team to break the deadlock and win the game.
Northland were on the back foot again on Tuesday after conceding an early goal to Capital.
Wellington dominated the first half and the majority of the match except for a brief spell after the break, during which Hannah Hill equalised from a penalty corner.
Capital scored again but Northland coach Bevan Gibbs said they might have scored more but for the efforts of goalkeeper Brooke Roberts.
But in the end, Gibbs said, Capital were fortunate to take all the points when they pulled off Roberts in a last-ditch effort to equalise, with a couple of Northland scoring chances going close.
Yesterday Northland completed pool play against Canterbury, losing 0-4.
