A Mount Maunganui surfer placed second in the finals of the Women's Longboard Division at the 2017 National Surfing Championships at Piha.

Kea Smith contested her semi-final heat strongly on Wednesday, coming first with a score of 8.17.

However, in the finals it was Mischa Davis of Piha who took out the top spot, even though Smith had previously beaten her in their semi-final heat.

In the Over 55s Division, Mount surfer Phill Griffin also came close to winning the final, scoring an 8.0 point ride on one wave to almost knock the frontrunner Garry Pike (Piha) off his perch.

However, it wasn't to be, with one point separating the two at the podium, and Griffin settling for second.

The surf was the smallest of the week with a 1.0m swell and light variable winds for much of the day making a pleasant change from the relentless westerly winds experienced over the first three days of the competition.

While eight titles were awarded, the premier divisions of the Open Men's and Women's endured another lay day as organisers eye up a significant swell on the final two days of the event.

The swell is expected to remain the same size for today with a 1.0m swell. However the wind is forecasted to swing to the northwest and increase throughout the day offering deteriorating conditions. A call on the order of events will be made at 7am with a possible 8am start.
