Brownlee stepped down as Christchurch Regeneration Minister after last December's Cabinet reshuffle and was replaced by local MP Nicky Wagner, whom Manji did not explicitly criticise.
"Who is holding the vision and who is leading it?" Manji asked. "I would say no one. When John Key stepped down at the end of last year, I really felt we had lost the one person who at least could appreciate the big picture and understood the strategic imperative for a successful recovery of Christchurch.
"Christchurch matters. Our country, one nation, two islands is suffering from a lack of balance, as resources and people are sucked into Auckland, to the detriment of the rest of the country, " said Manji. "We have new infrastructure, an oversupply of commercial space, we will have a new range of brand new community facilities and our housing is generally affordable housing as well. This narrative needs to be pushed harder and more explicitly."
The city also had options about how it developed areas as yet unbuilt, with opportunities to review the five year-old post-quake Blueprint for the city and the vision behind it.
"What was the objective? Why reshape the city and engage in the largest compulsory acquisition process in modern times?"
Bidding for the 2026 Commonwealth Games, 52 years after the 1974 Friendly Games, would give the city "something to aim for, something to dream about" as both a demonstration to the world 15 years after the quakes what Christchurch has achieved.
"It can be shaped our way, with Christchurch as the host city, but with the games spread throughout Canterbury and even the South Island. We are building everything we need and we have time to prepare. This will be the icing on the cake, a lofty goal to give us something to really focus on and be excited about."
Manji is backing his call with a specific plan to spend another billion dollars to finish a range of key projects throughout the city, whose future has become doubtful but would complete much of the rebuild, and which he would advocate for in Parliament.
A $400 million Central City Housing fund would build high density neighbourhoods in the city's so-called East Frame, which Manji said had been "clear felled"; $300m for a Red Zone redevelopment fund, where projects are in development but have no funding; $200m towards a Multi-Purpose Arena which should be built immediately and well, and a $100m City Revitalisation fund that could establish a range of new facilities including a marine research centre at New Brighton, an indoor velodrome on the site of Lancaster Park, a national sports museum, a science and innovation centre and an 'epic centre' for youth.
While approached to stand for The Opportunities Party, Manji has chosen to remain independent, meaning he can bring no more than his own vote to the next Parliament, making him a potential partner for National, which may struggle for a majority with its existing coalition partners, the Maori, United Future and Act parties, based on current polling. He would willingly work with a Labour-led government.
Brownlee would return to Parliament as a list MP, having held Ilam continuously since 1996.
