Arrangements are still being made to return the body of Jerry Collins to New Zealand.

His three-month-old daughter Ayla remains in intensive care a Montpellier hospital after losing her father and mother in Friday's car crash.

French-based former All Blacks Neemia Tialata and Chris Masoe have been by the baby's side.

The parents of Jerry Collins are on their way to France to be with their granddaughter.

Ms Madill's sister has flown in from Canada.

About 1500 people have marched in silence around the town centre of Narbonne in France, in a tribute to Jerry Collins.

Those walking did so behind a giant photograph of the flanker.

They included Chris Masoe - who plays for Toulon - and some of his Narbonne teammates.

Many of the mourners were dressed in the orange and black colours of Narbonne, with some laying bouquets of flowers at the base of the photograph, which was placed outside the club stadium.

Discussions continue in Wellington as to how best remember Jerry Collins.

Among the ideas are naming Porirua Park and aisle six at Westpac Stadium in his honour.

Westpac Stadium CEO Shane Harmon likes the idea, but says it's something to look at further down the track.

"We don't feel that now is the appropriate time, and we wouldn't do anything without consulting the family, but certainly we will consider the idea."
