New Zealand domestic rivals Auckland City had won the previous seven regional finals between 2011 and 2017 - including three straight against Team Wellington - of which four were held over two legs and three were one-off matches.
The Champions League quarter-finals will now be held on a home-and-away basis, after the four group winners hosted one-off matches in 2018.
Vanuatu, Fiji, Solomon Islands and New Caledonia were selected to host the Group Stage, in February and March, at a meeting of the OFC Executive Committee in Auckland at the end of October.
"All the Member Associations have an opportunity to indicate their interest in hosting the different competitions OFC has on the annual calendar and for 2019 we had a great response," said OFC Competitions and Events Manager Michael Song.
"The competition department took each expression of interest into consideration, keeping in mind key criteria in order to make recommendations to the Executive Committee and we are pleased that the members were able to support those recommendations."
The 2019 OFC Champions League gets underway at the end of January, with the Cook Islands hosting the Qualifier event for the first time in three years.
