I think Jim Bolger might be about to spark a debate. Two debates actually. One on our economic settings and the other on race relations.

He says neoliberalism has failed and suggests unions should have a stronger voice. He says Treaty of Waitangi settlements may not be full and final and that Maori language tuition should be compulsory in primary schools.

It was striking, sitting in Jim Bolger's Waikanae home for the third episode of The 9th Floor, just how many of the issues he grappled with in the 1990s are still alive and being debated rigorously today.

Adding to that sense of history was the fact that John Key resigned while we were discussing with Bolger what it was like to be a third-term National Prime Minister.

There was a little bit of personal history for me, too, and we'll come to that. But first the policy.

Bolger says neoliberal economic policies have absolutely failed. It's not uncommon to hear that now; even the International Money Fund says so.

But to hear it from a former National Prime Minister who pursued privatisation, labour market deregulation, welfare cuts and tax reductions, well, that's pretty interesting.

"They have failed to produce economic growth and what growth there has been has gone to the few at the top," Bolger says, not of his own policies specifically but of neoliberalism the world over.

He laments the levels of inequality and concludes "that model needs to change".

But hang on. Didn't he, along with Finance Minister Ruth Richardson, embark on that model, or at least enthusiastically pick up from where Roger Douglas and the fourth Labour Government left off?

Bolger doesn't have a problem calling those policies neoliberal, although he prefers to call them "pragmatic" decisions to respond to the circumstances.

It sets us up for the ride we go on with Bolger through the 1990s, a time of radical social and economic change.

Judge for yourself whether or not they were the right policies but do it armed with the context.

Bolger describes his 17-hour honeymoon after becoming PM in 1990. He recalls ashen-faced officials telling him before he was even sworn in that the BNZ was going bust and if that happened nearly "half of New Zealand's companies would have collapsed".

The fiscal crisis sparked the Mother of All Budgets and deep cuts to the welfare state.

Some believe this was the start of the entrenched poverty we agonise about to this day.

How does the man whose election slogan was "The Decent Society" feel about that now?

There is so much to the Bolger years. The first MMP (mixed member proportional) government with Winston Peters, the economic growth of the mid-90s, the birth of Te Papa and the first big Treaty settlements.

Indeed, Bolger is at his most passionate speaking about Maori issues.

He has a visceral hatred of racism and explains the personal context for that.

We asked him whether future generations will open up Treaty settlements again, given Maori got a fraction of what was lost, or whether they are genuinely full and final. He says it is a "legitimate" question and "entirely up to us".

If Maori are still at the bottom of the heap "then you can expect someone to ask the question again because it means that society has failed".

He is also scathing of former National leader Don Brash's Orewa speech on "Maori privilege".

"It wasn't anywhere near as bad as Trump but it was in that frame."

Of course, Don Brash never made it to PM, replaced by John Key in 2006. "Gone by lunchtime" was the political phrase popular at the time.

When we returned to Bolger's house after our lunch break, Key was gone, too, one of those rare times when "shock resignation" is an accurate headline.

Bolger was buzzing as we talked long into the afternoon, feeling fate had settled in with him on the big chair in the lounge of his stately home.

I felt it too. My first day as a political reporter was Bolger's last day as an MP.

I was asked to cover the valedictory for the Evening Post, a task I felt hopelessly ill-prepared for.

In his parting words to Parliament in April 1998, Bolger looked up at the Press Gallery and invited us to "take out your quills and bury me one final time".

We've done the opposite here, I hope, and dug up the past for The 9th Floor.

It's 19 years later, almost to the day, and I think we're all a little bit better prepared to look at his legacy.
