Mr Shearer acknowledged the Labour Party had more work to do on maintaining its alliance with Ratana, which began under Labour leader Michael Joseph Savage in the 1930s.
He invited Ratana elders to Parliament to discuss the future of their union, and pointed to current MPs Rino Tirikatene and Louisa Wall - both Ratana morehu (followers) - as examples of Labour's commitment to Ratana. "I know we have to work harder on that relationship - I acknowledge from our side that we have to do that ... It can't just be done on one day a year on this paepae."
It was an implicit acknowledgement of something Ratana has accused Labour of in the past: that it had taken the movement's support for granted.
In return, Ratana did not shun him - nor did they openly embrace him.
Instead, Ratana's Waaka Palmer delivered a message from the church tumuaki [president], Haare Meihana, telling Mr Shearer it was time to review the alliance, and the church now had to take account of the greater political diversity of its people.
Following the speeches, Ratana secretary William Meremere said that although the church had a formal view, its morehu were free to vote as they wished and now significant groups backed the Maori and Mana parties.
Mr Meremere said: "It is encouraging that they recognise there is work to be done over the coming months and years. There are things to be done, fences to be mended. What we are asking is that we do it together."
Prime Minister John Key claimed later the links between Labour and the church were "well and truly gone".
"In reality, from what I can see, Maori are no different from any other New Zealanders - they're going to vote for what they think can deliver the best outcomes for them."
He also told those at Ratana that despite the alliance with Labour, in his view it was National which had delivered more to Ratana when it was in government, citing new housing at Ratana Pa and renovation of old houses.
Otherwise, the main theme that the Ratana speakers put before the politicians was poverty. They used the opportunity of having the ear of the Prime Minister to outline their desire for the Government to address poverty.
Mr Key responded with a serious speech, speaking of the times the country had seen over the past year, and the Government's proposed welfare reforms, and education and health measures to help address poverty.
There were two consolations for Mr Shearer: the Prime Minister had to wait for over an hour in the hot sun while the powhiri for Labour was held before he was welcomed on the marae.
The second was that his joke was better than Mr Key's, which was to claim credit for bringing the sunny weather to the occasion because the sky was blue, like his party's colour.
