"Jacinda has a real way about her. She is a warm, engaging and delightful person who is also very determined."
When asked whether changing leadership so close to the election would be an issue Mr Nash said the benefits outweighed the risks.
Labour's Tukituki candidate Anna Lorck said Ms Adern had a natural ability to connect with people from all walks of life.
"Her relentless positivity is infectious; she has great wit and I believe she will be unstoppable. When it comes to getting the young people out voting, Jacinda will do it, my daughters adore her"
Ms Lorck said she was incredibly excited about the weeks ahead.
"We are in for the campaign of lives."
Wairarapa Labour candidate Kieran McAnulty was also delighted with the new leadership team and said he supported them 100 per cent.
"I know Jacinda well. I have worked with her closely on Labour's Policy Council. She is an unrivalled communicator and has an amazing ability to engage with people. Kelvin Davis has strong provincial credentials, coming from Northland."
However Mr McAnulty admired Mr Little for making what must have been a very difficult decision.
"It was a gutsy and selfless call which puts the party and the country before personal ambition.
"It must have been tempting to hang on in and hope for the best. But that is not the type of bloke he is. Whenever people have asked me about Andrew I have said what I knew to be true - he is a man of integrity."
Labour's Ikaroa-Rawhiti Meka Whaitiri agreed with Mr McAnulty and commended Mr Little's call to put the party ahead of himself.
"I respect what he did and I think it is now an exciting time for Labour, as Jacinda and Kelvin offer a different look.
"Jacinda will appeal to the young people and women voters and Kelvin is the first Maori deputy leader so it is historic."
National Tukituki candidate Lawrence Yule said this new duo for Labour didn't change anything with the way he or the party was operating.
"We have got a solid and unified National team and what Labour does is no concern to us as we have our game plan and are sticking to it."
With regards to the change so close to the election Mr Yule said it could be damaging to any party but that was for them to work out not National.
National Napier candidate David Elliot also said it made zero difference to his campaign and he would continue doorknocking and listening to his constituents.
"The change simply underscores the stability of the National Party. At least the local candidates don't have to change their billboards."
