Each week The Front Page takes you behind the scenes of the biggest story from the New Zealand Herald and Newstalk ZB. Today it's whether we can trust polls any more. Hosted by Frances Cook.

People love to rag on political polls, and for the latest lot, they might actually have a point.

Newshub and 1 News released polls on the same night that showed drastically different results. One where Labour plummeted and National came out ahead, the other where Labour could govern alone.

What on earth is going on, and how can two reputable polls have such entirely different results?

It's not the first time either, with pollsters missing Brexit, and the election on Donald Trump.

Polls have long been a way to check the mood of the nation, and sometimes important decisions are made on the basis of them.

But now you could be forgiven for thinking we should give up on them entirely.

Herald reporter Damien Venuto has investigated this, and the answers are fascinating.

We discussed the many elements that can make a poll go wrong, and how the experts want to change things.
