First, the campaign committee has to come up with a new tag line to replace the "Fresh approach'' gracing the old billboards with ex-leader Andrew Little and Ms Ardern.
The bounce in donations in small amounts to the party will help to pay for a new batch.
Labour general secretary Andrew Kirton said the party had received about $150,000 online in the 24 hours to 2pm yesterday.
Another $100,000 had come in off-line and about 1000 had contacted the party to volunteer.
"I feel a huge sense of responsibility from that,'' Ms Ardern said yesterday at Parliament.
"That's people reaching into their back pocket and giving their hard-earned cash to what we are fighting for in this campaign ...''
But the billboard transition was not going to happen within days.
"There is going to be a delay,'' she said.
"Just logistically, printing, dispatching, getting them up, it is going to take a bit of time. It could be a couple of weeks.''
She confirmed deputy leader Kelvin Davis would be No2 on the party list, as required under the constitution.
The Te Tai Tokerau MP, along with the other five Maori electorate MPs, had previously elected to stay off the list.
"We don't have time to be playing with the constitution right now,'' Ms Ardern said.
She had not discussed Mr Little's role nor list place with him but said at her first press conference she wanted him to be on the front bench (in Labour that is the top 12) and she wanted him in any Labour cabinet.
"I don't expect there to be many changes at all to the line-up of the senior Labour team.''
She had nothing to report on the 72-hour stocktake of policies and campaign approach she foreshadowed after being elected on Tuesday. But it may involve enhancements to its student policy.
"That's an area I want to have a little look at but nothing specific right now.''
