The All Blacks will play Fiji at Carisbrook in Dunedin in July, despite New Zealand Government travel bans on some Fiji officials following the 2006 military coup.
The “last” test at Carisbrook will be played on Friday July 22, ahead of the Tri-Nations series, and is also being seen as a warm-up for both sides preparing for the Rugby World Cup starting September in New Zealand.
All Blacks Coach Graham Henry said the test would be a key match for the All Blacks.
"It's important that we have a game together as a team so that we can reignite and build on our combinations again and give the players the best possible preparation and kick-off to the season, so it's fantastic that Fiji has been confirmed," he said.
"We are also delighted that we can raise money for the people of Christchurch, who are still very much in the team's thoughts.”
NZRU chief executive Steve Tew said final confirmation of Fiji as the All Blacks' opponent had been delayed as the NZRU worked through issues relating to the New Zealand Government's travel restrictions on some Fijian citizens.
"The NZRU has not asked the New Zealand Government for any exemptions to the travel ban in place. The Fiji Rugby Union will field a competitive team within the parameters of the travel ban and see this Test as a major build-up for their Rugby World Cup campaign, while the Fijian Government has confirmed they have no objections to the team travelling to New Zealand for the match."
Mr Tew said as well as the fundraising effort, a number of other initiatives were planned to show support for the people of Canterbury.
"Otago and Southland fans get priority access to Dunedin test tickets but we will also be offering the Canterbury rugby community and then all Canterbury residents the chance to buy tickets before they go on nationwide sale.
"We will also be looking to host representatives from the Canterbury earthquake rescue, recovery and relief teams to give them a break, a night out at the rugby and to thank them for all their efforts.
"We were keen to have the extra test in the South Island to give Christchurch residents and other South Islanders the chance to see the All Blacks in action this year so hopefully they get to do that and we can raise some money for Christchurch as well," Mr Tew said.
The All Blacks have played Fiji eight times since 1974, with the last test in 2005 at North Harbour Stadium.
