Weepu (25) played for Wellington in the tournament last year in a bid to gain fitness and it is thought he will repeat the move as he builds for the 2009 Super 14 season with the Hurricanes.
The tournament is normally a no-go zone for current All Blacks but Weepu is reportedly keen to be involved again.
If he plays, the nuggety halfback will be hoping his appearance this year will be as beneficial to his career as last year's was.
Weepu was on the outer at the start of last year, after being dropped from the World Cup squad.
But he fought back, starting at the Queenstown event and was eventually recalled to the All Blacks, also leading Wellington to take the Ranfurly Shield.
Weepu returned from the All Blacks' end-of-year tour only a month ago, and most of his national team-mates are still on leave.
Wellington is in a tough pool, facing off against defending champion Auckland, heavyweight Canterbury and Otago Country, with only the top two teams going through to the cup round.
New Zealand sevens coach Gordon Tietjens confirmed he would be at the tournament over the weekend and said the new experimental law variations for the 15-man game meant sevens was becoming more like the larger version of the game.
"The way the new rules have changed the game, it makes good sevens players easily able to adapt to 15s," Tietjens said.
"The game is speeding up and those who play well in sevens can complement those skills at the Super 14 level."
Tietjens said sevens was a good game for Weepu as it kept fitness levels up and skilful players such as the Wellington halfback should excel.
He said there were chances for both backs and forwards to be selected in the next national squad for the sevens tournament in Wellington next month.
Tietjens said he was happy with the performance of the New Zealand team in the first two IRB tournaments, despite its not winning either event.
New Zealand lost in the semifinal to England in Dubai and lost to host South Africa in the final in George last month.
Tietjens will name a 28-man squad straight after the tournament for a training camp in Mt Maunganui later this month.
Tietjens had praise for Otago loose forward Paul Grant, who made his debut for New Zealand in the two previous tournaments.
He said Grant had good pace and size and had shown some real ability in the two tournaments so far.
