"It enables kids that wouldn't necessarily come due to the cost of food to get along to the game."
The initiative has garnered a large amount of interest and it's something that the NRU will be looking to continue.
"We will prolong this initiative in some form for the Mitre 10 Cup. The Barbarians themselves have been a huge help for this."
Meanwhile, Northland Barbarians coach Richie Harris and Blues coach Tana Umaga have named their respective sides for tonight's clash.
Three Northland players feature for the Blues in this match: flanker Kara Pryor, hooker Matt Moulds and prop Namatahi Waa.
New Blues signing Josh Goodhue will run out at lock for the Barbarians side.
Umaga said the game is an opportunity for the team to practice their combinations and work flow on the field before the season recommences.
"Northland Rugby Union is providing a great opportunity for us to get on to the field and have a good hit out, especially as we haven't played together for three weeks," he said.
"We're taking everything in to this game that we would into a regular season match.
"The boys have been training pretty hard and I know they're all ready to get back onto the field and play as a team."
The June international window has been an opportunity for players and coaches to gain some representative experience.
The fixture will be good preparation for the Blues ahead of their final three Super Rugby games, while is offers a chance for Northland players to press their claims for Mitre 10 Cup selection.
The game kicks off at 6:30pm.
