The cluster of king tides hitting the Bay of Plenty proved too much for one Auckland woman who dislocated her hip while admiring the ocean from the Omanu sand dunes.

The woman, believed to be in her 50s, was attended to by a group of Omanu Surf Club members responding to the call from a nearby bystander on the beach on Saturday night.

Omanu Surf Club swim coach Nick Ayers says the woman and her partner were making their way back from the beach to a holiday home at 9.30pm when she fell.

About seven surf club members helped to stabilise the woman until paramedics arrived.

'The lady dislocated her hip in the dunes about 100 metres from the surf club towards Papamoa. I think they had come down to look at the surf,” says Nick.

'We took the quad bike and stretcher down and gave her some first aid and told her not to move. We called the ambulance and they extricated her and it was all done by about 11.30pm.”

St John Ambulance territory manager Ross Clarke says the woman was transported to Tauranga Hospital in a stable condition with leg injuries.

According to NIWA the biggest of the king tides hitting the Western Bay of Plenty from February 1-4 occurred on Saturday night. A king tide is the very highest tide that occurs naturally.

Land Information New Zealand Saturday's high tide sat at 2 metres, rising to 2.1m on Sunday. It is expected to subside to the average high tide mark of 1.8m on Friday.

But it is the surfers making the most of the tides that brought impressive sets of waves, especially on Saturday afternoon.

NZ Surf School head instructor Al Le-Grange says the king tide's resulting 4 foot swell made for 'happy days” with ideal surfing conditions for all abilities.

Al says on Saturday he noticed between 60 and 80 surfers riding an array of waves at Mount Maunganui's Main Beach during the high point of the swells.

'On the Saturday we had a relatively busy day. I think surfing wise it made it quite difficult because the waves were quite big too. There were some impressive sets coming through,” says Al.

'We had a few lessons when the tide was high and the waves were smaller. We had some decent sets of waves all along the coasts the rest of the day; it was great.”

Surfing New Zealand contest director Ben Kennings says waves at Mount Maunganui were 'as good as it gets” for competitors in the Billabong Grom Series at the weekend.

'That afternoon [Saturday] they really built, and the swell probably tripled in size compared with the morning. The wind was alright and it was really good waves,” says Ben.

'And most of the competitors couldn't believe it because usually when we are at the Mount it's kind of small, but it was really impressive.”

Around the rest of the city marine officials are reporting a quiet weekend on the water with many people preferring to stay on the beach.

Mount Maunganui Lifeguard Service club manager Shelley Kerr says despite the large surf there was nothing out of the ordinary.

Coastguard Tauranga operations manager Simon Barker says the tides caused little disruption further out at sea.

'Saturday was a bit windy out there. But other than that it was pretty quiet and has flattened off by Sunday morning,” says Simon.

'I think it was about 25 knots, that's what we were expecting. I haven't seen the reports but it was pretty gusty; everything is pretty calm again though.”
